Range-finding sensors have applications that span several industries, from metrology to robotic control. Frequency-modulated continuous-wave (FMCW) lidar has been proven effective in providing high depth resolution, but suffers from limited range due to short coherence length of tunable laser sources. In order to expand into more markets, FMCW lidar needs compact and inexpensive implementations to improve the performance of tunable lasers. We have demonstrated the use of optoelectronic phase-locked loops (OPLLs) and "k-clock resampling" methods to make compact and inexpensive FMCW lidar which is useful for manufacturing applications and some consumer-grade applications such as 3D facial reconstruction.
