| 内容記述 | 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 are for transmissive signals. Best results are obtained using high ratio filters and high contrast signals. Signal extension derived from diffusely reflecting material objects is treated. By the use of 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 on signal characteristics is discussed. |
