No-scanning 3D measurement method using ultrafast dimensional conversion with a chirped optical frequency comb

Abstract A simultaneously high-precision, wide-range, and ultrafast time-resolution one-shot 3D shape measurement method is presented. Simultaneous times of flight from multiple positions to a target encoded in a chirped optical frequency comb can be obtained from spectral interferometry. We experim...
