STRAY LIGHT MITIGATION IN OPTICAL SYSTEMS

Methods and apparatus for stray light mitigation in optical systems that include two or more illumination sources (e.g., point light sources such as light-emitting diodes (LEDs)) that illuminate an object to be imaged, and a camera configured to capture images of light from the point light sources reflected by the object when illuminated. To mitigate "occlusions" or artifacts caused by, for example, stray light or reflections of the illumination sources off of other components of the system, multiple images of the object are captured with different groups of the illumination sources enabled. The captured images can then be processed and merged to generate an output image with the occlusions or artifacts caused by stray light or reflections mitigated or eliminated.
