Paper Abstract

In this paper we report on research concerning triple correlation of laser speckle patterns produced by illuminating a distant rough object with coherent light. Triple correlation of these speckle patterns is known to contain Fourier phase information. In our work the Fourier phase of an object is extracted by treating the phase triplet in the factorized form of the triple correlation as a binary quantity. The Fourier phase along with the Fourier magnitude, obtained by second order correlation, yields an image via inverse transformation.
