In this paper, a novel velocimeter based on laser self-mixing Doppler technology has been developed for speed measurement. The laser employed in our experiment is a distributed feedback (DFB) fiber laser, which is an all-fiber structure using only one Fiber Bragg Grating to realize optical feedback and wavelength selection. Self-mixing interference for optical velocity sensing is experimentally...

Abstract The development of a low-cost Video Velocimeter (VIV) to estimate underwater bulk flow velocity is described. instrument utilizes simplified particle image correlation technique reconstruct an average vector from video recordings ambient particles. VIV uses single camera with set mirrors that splits the view into two stereoscopic views, allowing estimation vector. was validated in cont...
