ABSTRACT:
In an actively illuminated imaging system, illumination of a segmented scene is synchronized with an image sensing period. A scene is segmented into a plurality of scene portions utilizing a segmented lens. In an aspect, a first scene portion is illuminated when an imager is actively collecting photogenerated charge from the first scene portion, and a second scene portion is illuminated when an imager is actively collecting photogenerated charge from the second scene portion. The sensitivity of an image sensor is maximized, while simultaneously minimizing the amount of light that must be supplied to illuminate a scene. An irradiance pattern is varied allowing a more uniform distribution of light. Bands of varying wavelength, polarization, and light intensity may be variously applied to illuminate individual scene segments, as needed to enhance an identification of an object in the scene. The present invention is particularly useful with high frame rate imaging systems.
