A Field-Worthy Profiling Fiber-Optic Diode Laser Doppler Velocimeter,
Abstract
A prototype prefiling fiber-optic Doppler velocimeter (FODLDV) for flow measurements in coastal waters was developed, fabricated, and testbed in the laboratory and in the field. The two-component FODLDV, a backscattering version of a field-proven diode laser Doppler velocimeter (DLDV), consists of a fiber optic probe and link, an optronic module, a digital fast fourier transform-based signal processor, and a data acquisition and control system. The fiber-optic probe and link are mounted on a traverse that facilitates velocity profiling up to a range of 3 m, operating in a move-stop-and-sample mode from a stationary platform. One of the components was tested extensively in the laboratory. (Author)
