Abstract: Due to the ability of terahertz (THz) waves to penetrate nonpolar opaque optical materials, Doppler interferometric velocimeters using THz waves can measure the velocity of a target inside ...
Abstract: We propose a two-stage Doppler compensation method for 100-Gbit/s inter-satellite laser communications. We experimentally demonstrate its better Doppler shift tolerance and ~2.5(0.5) orders ...
Polytec's optical measurement equipment focuses on dynamic response measurements. MEMS devices typically have actively moving ...
