Abstract

The LDA is distinguished from conventional velocity transducers by the fact that it measures the velocities of individual particles or groups of particles rather than the fluid velocity. This requires special methods of analyzing the LDA signal in order to extract properly the information about the flow field and its statistics. In particular, special methods for computing time averages are needed. The purpose of this paper is to identify the pitfalls, to present the best available methods for analysis, to discuss the interpretation of LDA measurements, and to describe the effects of ambiguity noise in high burst density signals.
