Paper Abstract

Phase reconstruction algorithms, which determine phase from measured phase differences, are used in several areas, such as adaptive optics and speckle imaging. The purpose of this study is to examine the effects of noisy phase difference measurement inputs on reconstructor output phase noise. An analytic procedure for finding the probability density function, and hence the variance and gain, of the output noise in a general phasor-based path averaging operation is given. Also, noise performance comparisons between the phasor-based and optimal linear techniques are shown.
