Abstract
A system (100) for gating a sensor (118) includes a detector (120) that detects light and outputs a signal (102) corresponding to the light. A control unit (134) receives the signal (104), adjusts a gating signal (112) in response to the signal (104), and outputs the adjusted gating signal (112) to gate a sensor (118) sensing the light.
