Paper Abstract

The relevant issues in the design of laboratory experiments to demonstrate phase retrieval from Fourier intensity (far-field speckle pattern) data from a laser-illuminated diffuse object are considered. Based on the results of these considerations, a demonstration phase retrieval experiment was conducted. A diffuse object was coherently illuminated, Fourier intensity data was collected and an image was reconstructed by the iterative Fourier transform algorithm using the Fourier intensity data and an a priori known triangular image support constraint. The intensity of the complex-valued reconstructed image compares favorably to a conventional image with the same spatial frequency bandwidth, thus providing an experimental demonstration of the phase retrieval method.
