Abstract

A phase retrieval technique utilizing a differentiation filter in a coherent processing system has been developed and tested. The image irradiance produced in this system is quadratic in the partial derivative of object phase with respect to an object coordinate parallel to the transmittance gradient of the filter. Given a properly chosen set of such image irradiances it is possible to solve for the object phase.
