Abstract

In this work we exploit entangled twin-beam to enhance quantitative phase retrieval of an object in a non-interferometric setting, only measuring the propagated intensity pattern after interaction with the object. The scheme achieves full field phase reconstruction with quasi-single-shot acquisition, not requiring time consuming raster-scanning of the sample. In our experiment a 40% improved precision has been achieved with respect to the corresponding classical scheme.
