A Compact Programmable Laser Doppler Velocimeter for Marine Applications

Abstract

The purpose of this program is to research and develop a new laser Doppler velocimeter for deployment in the ocean. The system must be programmable and autonomous, and must operate unattended over periods of six months. The system will ultimately operate in highly dynamic shallow water environments and must be capable of providing magnitude and direction of the velocity distribution in two directions and associated flow turbulence as a function of time. The system will be utilized to measure sediment motion and a variety of ocean transport phenomena in highly dynamic situation. (JH)
