Abstract

Experimental and theoretical results describing matched filter selectivity for a particular class of signal as obtained, for example, in holographic velocimetry are reviewed. An experiment showing noise rejection is described for filters having both low and high ratios of signal to reference beam. The data presented are for transmissive signals. Best results are obtained using high ratio filters and high contrast signals. Extension to signals derived from diffusely reflecting material objects is treated. By utilizing proper optics, the scale change effects of matched filtering are shown to give a quantitative measure of deformation of the strained object. Dependence of sensitivity upon signal characteristics is discussed.
