Instrumentation for LDA signal processing
Abstract
An overview is given of the various signal processors which may be used in laser Doppler anemometry. The emphasis is on a comparison of the signal processors from the user's point of view. Guidelines on the performance of the instruments are given, to provide the potential user with the information necessary to choose the signal processor most appropriate to his application. The most important factors in the choice of instrumentation are presented, and a brief comparison of seven instruments on the basis of these factors is given.
