Abstract
We present results obtained from the application of a novel phase retrieval algorithm on experimental scattering data from a microlens array, with the aim of reconstructing the phase profile across the array. The algorithm, originally developed for electron microscopy, requires two intensity measurements at different distances from a weak scatter, where the total transmitted field is composed of the coherent sum of an incident plane wave and the scattered wave. The algorithm is noniterative and does not have the convergence problems associated with iterative algorithms. Our results obtained using the new algorithm on experimental data are comparable to those obtained with the Gerchberg-Saxton algorithm, and the computational cost is much less. The new technique shows great promise for inverse scattering applications, such as optical diffraction tomography and rough surface profiling, where the scattering can be assumed to be weak.
