Abstract
The application of multiple exposure photographic techniques to the measurement of fluid velocity fields is described, and pulsed laser velocimetry (PLV) is discussed in the context of fluids measurements. Various methods of analyzing the image data to extract the velocity are presented, and the theory for signal processing via spatial correlation of the displaced image data is derived. This theory is appropriate for the analysis of turbulent velocity field data although only laminar flow is considered. The practical and theoretical constraints governing the spatial resolution, temporal resolution and accuracy of PLV systems are presented, and related to the performance parameters for practical systems.
