Research Abstract

We investigated 3-D range-finding techniques with ambient illumination robustness. We introduced demodulation technique into light-section method, and with design optimization, we demonstrated -40dB background-light suppression performance by simulation. We have designed time-encoded 2-D pattern projection method with ambient illumination rejection techniques, and fabricated using advanced 65nm CMOS technology. We demonstrated dynamic range over 80dB with background suppression of -21dB. We also demonstrated 10 rangemap/sec 3-D range-finding performance at SBR or -5.5dB.
