Abstract

Abstract: An experimental study of the use of lasers in measuring flows associated with compressional waves has been undertaken. A prototype differential laser Doppler system amenable to a variety of design modifications has been assembled and tested on single frequency wave fields in a water-filled standing wave tube. The use of polarization preserving fibers in the laser Doppler velocimeter (LDV) can lead to both (1) a very compact design for the optical measuring head, and (2), novel signal processing capabilities. The discussion is illustrated with experimental data obtained with a 1 watt argon-ion laser.
