PARTIALLY COHERENT PHASE RECOVERY

摘要

A system and method for incorporating partially coherent illumination models into the problem of phase and amplitude retrieval from a stack of intensity images. The recovery of phase could be realized by many methods, including Kalman filters or other nonlinear optimization algorithms that provide least squares error between the measurement and estimation.

1. A system for phase recovery of an intensity image with partially coherent illumination, the system comprising:
(a) a computer processor; and (b) a memory storing instructions executable on the processor; (c) the instructions, when executed, performing the steps comprising:
(i) mathematically modeling partial coherence with respect to the intensity image;(ii) formulating a state-space Kalman filter from the partial coherence model; and(iii) applying a standard Kalman filter to the state-space Kalman filter to estimate a phase with respect to the intensity image.
