Phase-Based Multi-Tone CW Lidar: A Technique for Ranging Beyond the Coherence Length of the CW Laser

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally demonstrate ranging and velocimetry at >500× beyond the coherence length of a CW laser in a technique called phase-based multi-tone continuous-wave lidar that eliminates the need for any form of phase or frequency sweeping.
