WebApr 18, 2024 · The optical backscattering from particles in the ocean is an important quantity that has been measured by remote sensing techniques and in situ instruments. In this paper, we compare estimates of this quantity from airborne lidar with those from an in situ instrument on an underwater glider. WebA novel distributed sensing technique based on reflectometry is proposed. The technique uses the interference of the light waves backscattered within the resolution range of a reflectometer to detect the optical path changes in a single-mode fiber. Experimental results are presented, and practical realization of an intrusion detector that employs this …
