Abstract

We demonstrate a profilometer composed of an ultra-stabilized mode-locked frequency comb laser and a single pixel camera based on compressive sensing technique to measure a profile of an object. The use of two harmonics of the laser repetition enables us to measure an object with a depth of more than 1 meter without 2π phase ambiguity.
