Stabilising system for missiles

Device for measuring the movement and / or position of a mechanically controlled (1) or provided with a self-propelled at least vehicle, one of its six degrees of freedom in space using an optical detection device, said device comprising an optical projection (2) arranged in the vehicle (1) through which can project an image of the environment (4) by sectors on a focal plane and a displacement sensor optoelectronic (3), the displacement sensor optoelectronic (3) comprises at least a chip - projection optics (2) designed and arranged such that they can project away structures at infinity on the movement sensor (3), characterized in that being intended for use in optical mice or having the same structure as these, - introducing the chip, first, one surface provided with multiple photosensitive cells exploration and, on the other hand, an electronic digital evaluation reading signals photosensitive cells with a reading frequency, evaluates these signals to recognize image displacements of structures designed and is made to emit a measurement signal for image shift.
