Abstract
A simple technique for measuring the random noise of an interferometricmeasurement is presented. The method is based on a filtering technique andthe use of a low-pass convolution kernel. It is shown that the method givesa deterministic fraction of the real noise present in the experimentaldata. The evaluation of the probability density allows the determination ofthe enlarging constant for specifying the confidence level. Experimentalresults are reported in the case of moderately noisy and significantlynoisy interferometric techniques: phase shifting interferometric testingof smooth surfaces and phase shifting speckle interferometry.
