摘要：

A general analysis of signal processing in electronic speckle pattern interferometry is presented. The effects of limited T.V.-camera resolution is included, and it is shown that the T.V.-monitor brightness is given by essentially the same expression as for full T.V.-camera resolution. One term in this expression is the fringe signal, while the others represent noise. The optimal reference-to-object intensity ratio, which maximizes the fringe signal, is determined and the dependence on the size of the aperture is given. The effect of a double slit aperture is compared with the effect of a circular aperture. © 1979 Taylor & Francis Group, LLC.
