The first monograph devoted exclusively to spatial filtering velocimetry, this book includes fundamental theory, imaging optics, signal analysis, spatial filtering devices and systems, plus applications. Also suitable as a tutorial for students and users who are unfamiliar with optics and signal processing, Spatial Filtering Velocimetry treats the principle and properties of this velocimetric technique in a concise and easily readable form, together with full appendices. The book reviews a wide range of systems and applications of the spatial-filtering technique for velocity and related measurements, putting forth examples useful in various fields of science, medicine, and engineering.
