The present invention relates generally to holographic sighting devices and, in particular, to a lightweight, waterproof, modular holographic sighting system that can be used on small firearms,

<p>5 Arches, telescopes, and other uses where guidance is necessary.</p>

Multiple sighting methods have been used to guide firearms in both commercial and military applications. Seeing through the eye requires the most basic, aiming to align the rear sight, front sight, and target while shifting the eye focus point between the front and rear vision pattern and the target. can be

Stereoscopic sighting systems, such as described in US Patent No. 6.490.060 to Tai et al., have become the preferred solution for shooters who require a high degree of accuracy with regard to rapid target acquisition. Specifically, hk;

L3- Manufactured by Holographic Weapon Sight (HWS)

5 Inc. EOTech Communications, the first system to take advantage of stereoscopic imaging technology to display a full reticle pattern at or near the target segment, creating a low-visibility solution that can be deployed quickly and in any lighting condition. EOTech's Holographic Weapon Sight Systems (HWS) were also the first to take advantage of similar wavelength dispersal technology that allows the use of laser 10 diode articulation over extended temperature ranges.

However, the HWS systems currently available suffer from shortcomings related to their design and manufacturing method. Current HWS products use an internal reticle positioning mechanism, which converts the system's achromatic geometry when routing adjustments are made, and thus includes the ability of wavelength dispersion compensation elements to function as requested. The result is that these vision systems will function 15 differently when used at temperatures other than those they were initially set to. In addition

Similar to reduced wavelength dispersion, current HWS products suffer from distortion of the reticle pattern as a result of mechanical stresses created by the internal adjustment mechanism. The wavelength that stabilizes a stereoscopic optical element is a plastic flexible element, creating a system that is 20 subject to the deflections of the wavefront caused by temperature changes to the stereogram and the mounting substrate. The resulting distortions can be observed as 'smudging' or an increase in the size of the point element used for routing. In addition, HWS products use a modular O-ring rubber gasket system that is pressed flat to isolate the stereoscopic optical components from the external environment. It adopts the effectiveness and reliability of the HWS hermetic system

25 The compressed flat rubber gasket with O-ring has a high repeatability process

manufacturing. Any variation stimulated by manufacturing methods and method of operation affects the completeness and effectiveness of the seal over time. The sealing system of the O-ring and the flat rubber is often under pressure conditions caused by changing the ambient temperature and pressure conditions, resulting in a continuous circulation of the housing bore pressure, which tends to make the flat-pack method prone to failure.

5 As a result, systems sealed in this way tend to leak, allowing moisture to penetrate

Holographic elements, resulting in fading of the retina image.

As a result, current HWS systems require higher densities of laser diode power to maintain desirable reticle brightness and have a significantly lower average battery life than competing red line products.

<p>10 Newer HWS products use an off-axis reflection primer to prepare the resulting light on the first holographic element. These boresight elements require careful removal of an off-centered section of a lens to be covered by a reflective element prior to use in a HWS. However, inconsistencies in the production of the off-centre segment introduce these deviations and increase production expenses.</p>

<p>15th In conclusion, current designs of HWS are lacking, and small changes in HWS systems are required</p>

The mount, optical path, lattice patterns, and battery type are completely redesigned and completely retooled to implement these changes.

Accordingly, there is a need for a lightweight, modular, fixed-wide range . Stereoscopic vision system

It has a wide range of temperatures, maintains a battery life comparable to other red point products, and has a window

<p>20 Large, wide view, takes up minimal rod space on a handheld weapon, and can be produced inexpensively and precisely at a large volume.</p>

system. The innovative vision element can be easily changed to configure different battery types. Innovative stereoscopic vision system models obtain best-in-class battery life (compared to current HWS systems on the market) by means of highly efficient optical components and electronics design.

In the innovative vision system, the housing is sealed in multiple ways; Be the first of those ways

5 Channeled Flexible Plastic Seal Provides a non-tight, fully encapsulated seal channel to protect interior elements from air out.

Referring now to the shapes, and specifically Figures 1a and 1b in which similar numbers are assigned to elements common to the shapes, the innovative vision system models introduce a projected laser light into a stereoscopic holographic wavelength compensation element over a surface area large enough to create larger viewing windows 10 24, Like the 1.4 by 1 inch (3.56 by 2.54 cm) above as shown in

Figure 1a. This is achieved by shifting the laser beam 10 emitted by a 32-diode laser module twice through a distance of about 70 mm before being paralleled by an aspherical surface. In innovative vision models, it will cover a 32 full width laser diode at a power density at half maximum (FWHM) of 30° by 10°

15th Surface area of ​​approximately 35 mm by 12 mm. In the preferred version of the invention, the folding surfaces or mirrors (12, 14) are dielectrically covered to reflect the maximum energy at a wavelength of 650 nm at angles of 45 degrees. To reduce weight and area, a section of the boresight surface is cut off in some inventive models .

A 15" 39" PRISM stroking laser results in and then a 20 18 stereoscopic transmission reticle. Then the scattered light produces a holographic image 26 and is diffracted with the same

fate. Because the dispersion of the two holograms is equal to opposite signals, it does not produce any bending of the beam that experienced twice diffraction with changes in the laser wavelength due to temperature.

Figure 1b is an example of what a stereoscopic vision system can become when stable temperature laser diodes can be used 32. In this configuration, it is

Light 10 from a 32 laser diode is projected by an 11 lens or reflective element and passes through a stereoscopic image 26 without producing a distortion due to a change in temperature.

It appears in the models of Figures 2A-2H. The operating plan 200 can be sub-divided into three major operating blocks. The first operational block is power management via a voltage regulator 202, and how all circuits are to be operated. The second operational block is a 206 microcontroller and how the microcontroller is used to form an interface to the components.

5 external. The third operational component is the adjustment and settings of the laser diode 32 via the laser controller 208. Each of these sub-circuits is described in detail below.

The operation of the innovative stereoscopic vision system models is achieved through the use of a power source such as a battery or a supercapacitor. Among the sources of operational power are here as the position of the AAA, AA and button battery types; For multiple chemicals that include illustratively

10 Alkaline, Lithium, and several rechargeable batteries, each alone or with several battery packs accumulating in series. The 38 battery power source modulation provides a voltage that is thus used to provide power to the switching voltage regulator 202. The voltage regulator 202 regulates the voltage to the level required to operate the microcontroller 206 and direct the laser diode 32.

15th Efficiency of the switch-operated voltage regulator 202 in reducing the current consumption of the system design for the innovative stereoscopic vision system. It is noticeable that emphasis is given to the use of a low series resistive capacitor at the output of the regulator 202 which powers the remainder of the electronics board

.36 board

In some embodiments of the inventive stereoscopic vision system, the voltage generated by the regulator 20 switched operating voltages 202 is provided to an 8-bit ultra-low power microcontroller

206 User to perform a variety of tasks. Once the innovative stereoscopic vision system is operational, the 206 microcontroller places itself in a reduced power state where there is only an external stop from the start/surge button on the 204 pushbutton controller capable of alerting the microcontroller 206. Prepare

25 The next step, as soon as the 206 microcontroller is alerted, is to check the operating voltage of the battery

6870

-12-

Voltage regulator 202, and compare battery voltage to internally generated voltage using a comparator. If the battery voltage reading is below the operating limit, the MICRO 206 will flash a laser diode 32 to indicate the battery is low and then the MICRO 206 will proceed to sleep.

5 Upon successful stimulation, a microcontroller 206 is then used to generate a pulse width modulation signal used to adjust the current level of the diode from the laser 32, and a modulation signal used to pulse the laser light 10 at a higher frequency thus providing power from the diode's high current consumption from Laser 32. High frequency modulated signals benefit from the fact that the diode of laser 32 is inherently less responsive to the rapid changes commonly seen in lasers.

<p>10 Its presence in digital fiber optic communications. The modulating frequency is adjusted using an internal timer or an output clock system, both of which are generated by a microcontroller 206.</p>

While in the operating state, the Micro-Control Unit 206 also handles push-button outages on the Push-Button Controller 204, which acts as a user interface for the innovative Stereoscopic vision system. And using the 206 push button controller, can

<p>15th The user turns on the stereoscopic vision system, increases optical density, decreases optical density, and turns off the system.</p>

The third operational component or electronics subsystem 36 is the adjustment and settings of the laser diode 32 via a 208 laser controller. In a specific embodiment, the diode control of the laser 32 is achieved by pure analog design of the PWM and . modes

<p>20 PFM. From the microcontroller 206, the PWM signal is first placed on a first-order RC filter (capacitance and resistor filter). Doing this allows a medium voltage to be introduced into an operational capacitor configured as a built-in used to overcome any sudden substitutions that can occur from the modulating part of the control for the diode of the 208 laser. Irreversible optical feed is provided back into the reflective foot of the operational capacitor, which allows the diode of the 32bm laser to monitor itself</p>

<p>25 And to prevent the current consumption from getting out of control and changing the diode of the laser 32. It helps </p>

6870

-13-

The feedback also compensates for small changes that can occur between the 32 laser diodes, as well as changes in temperature when the Innovative Stereoscopic Vision is turned on. The optical feedback is obtained from the generation of a photodiode current that is appropriately metered by a resistor that connects the optical diode to ground. In essence, it creates any current through

<p>5 The resistor has a voltage according to Ohm's law and this voltage is given retroactively inside the operational capacitor. Careful selection of an operational expander with a small input shift is also emphasized to reduce any inherent displacement when the voltage generated by the optical diode is too small and sensitive. The output of the operational capacitor is then fed into a bipolar junction transistor (BJT) allowing small voltages to be translated into a small current that is</p>

<p>10 Passed from the collector to the emitter, it achieves very low current consumption for stereoscopic vision since the control factor for this computation came from the true nature of the diode from the laser 32.</p>

Finally, the laser controller 208 is able to achieve higher optical powers and thus is not charged with current consumption of the diode from the laser 32 by using an inclusion circuit that controls a MOSFET transistor that secures a path to ground for the diode from the laser 32.

<p>15th Note that the response time of the diode of the laser 32 is much slower than the frequencies used</p>

To embed the laser diode 32 a large ground resistor 10 is used to trap the laser just below the optical lasing version. This gives the laser diode 32 a “start-up” whereby the laser diode 32 of the signal voltages system is fully grounded due to the current consumption required to provide that rapid response. And using his MOSFET

<p>20 “Logical Level”, the MOSFET can be directly exported as an interface to the 206 microcontroller where only the voltage limit is required to drive the MOSFET from off to on.</p>

Figures 4a-4c are a series of laser diode transmitter perspectives 70 and adjustment controllers 76 or screws that allow manual focusing of the laser diode 32 according to embodiments of the invention. As shown more clearly in the figures

<p>25 4a and 4c, the 32 laser diode is mounted on a laser . diode bus</p>

70 The diode carrier with a laser diode carrier 70 is attached to a 78 flexible circuit that allows the laser diode 32 to be aligned across the 76 alignment control units. The alignment controllers 76 attach the laser diode carrier 70 to the lower body component 80 of the imaging vision system models Innovative stereotaxic. And the diode bus of the laser 70 is loaded by

5 Springs are powered by 74 tensioning springs to remove hysteresis during focus, which is done on a focus body (not shown). The 74 tensioning springs provide external inclination to the laser diode transmission 70 corresponding to the tightening action of the 76 alignment control units. As shown in Figure 4c, which is a top-to-bottom cross-section view of a laser diode bus 70 to Figure 4a, which shows the relationship between the alignment controllers 76 and a diode bus

<p>10 Laser diode 70. As shown in Figure 4b, the focus of the laser diode 32 can be externally adjusted from the lower body component 80 with an alignment tool such as a hexagonal screwdriver, or other type of screwdriver or tool that can be inserted or engaged Inside the alignment controllers. When turned on, the user adjusts the laser diode vector focus direction of 70 by the alignment controllers 76, and when a correct or desired focus is achieved the screw is tightened</p>

<p>15th Fixation 72, thus fixing the diode bus of the laser 70 so that the diode of the laser 32 is in the center position.</p>

The optical bore seal is a closed bore conduit that provides a loose seal to be used with assembly housing components after all settings and adjustments have been completed. It is a consistent and reliable sealer that is not subject to the vagaries of the group's operation. Figure 4d.
