An optical system illuminates a spatial angular region during recurring illumination intervals. An optical receiver system acquires an image of the illuminated region. The receiver system acquires images during and between the illumination intervals. The images acquired during at least one illumination interval and one intervening interval are combined either in the optical receiver system or in an image processing device. #CMT#ADVANTAGE : #/CMT# Reduces effect of stray light. |
