Systems and methods for controling strobe illumination

Abstract

Systems and methods for strobe illumination of a workpiece are described. The systems may include an illumination source (310), an image acquisition device (200) and a control system (120). The illumination source (310) may emit visible, UV, or near-IR light as a transient flash to the workpiece, the transient flash occurring in response to a lamp trigger. The illumination source (310) may emit the light at an illumination intensity that rises from a begin threshold to a peak and afterwards diminishes to an end threshold during a flash duration. The image acquisition device (200) may capture the light associated with the workpiece for an exposure duration starting from an exposure trigger. The control system (120) may control the illumination source and the image acquisition device to synchronize the lamp trigger so that the exposure duration ends during the flash duration, such that a remaining portion of the flash does not affect the image exposure.
