ABSTRACT:
An active light source operating system (10,11) for a vehicle (14) includes a light source (50) that generates an initial illumination beam (54). A selective attenuation filter (27,52) forms an emitted illumination beam (56), with an associated light attenuation matrix (32,33), in response to the initial illumination beam (54). A sensor (31) detects an object and generates an object detection signal. A controller (35) is coupled to the selective attenuation filter (27,52) and said sensor (31). The controller (35) attenuates a pixel (104) in the light attenuation matrix (32,33) in response to the object detection signal.
