Abstract
A frequency-comb and MEMS-based external-cavity laser are integrated into a THz-bandwidth LIDAR system. Range to a diffuse target is measured at sub-msec update times, a comb-based precision/accuracy of 100 nm, and a resolution of 150 microns. Example 3D images are presented of a shoe and a face.
