Abstract :
The active range finder with 120/spl times/110 pixels achieves a projected light detection with high SBR (Signal-to-Background Ratio). The sensing scheme realizes a selective light detection under -18 dB SBR with a dynamic range exceeding 48 dB. The maximum frame rate is 2000 frames/s and the maximum range error is 1.5 mm at a distance of 1000 mm.
