Phase Retrieval for a Complex-Valued Object Using a Low-Resolution Image

Abstract

Phase retrieval from a single Fourier intensity distribution is very difficult for complex valued objects unless the object has a support that is very well known, has a special type of support, or has strong glints [1-3]. In this paper we show that even the most difficult types of complex objects can be reconstructed if one has a very low-resolution intensity image of the object to supplement the Fourier intensity data.
