Claim One:
1. A method of recovering unknown aberrations in an optical system, comprising: collecting intensity data produced by the optical system; generating an initial estimate of a phase of the optical system; iteratively performing a phase retrieval on the intensity data to generate a phase estimate using an initial diversity function corresponding to the intensity data; generating a phase map from the phase retrieval phase estimate; decomposing the phase map to generate a decomposition vector; generating an updated diversity function by combining the initial diversity function with the decomposition vector; generating an updated estimate of the phase of the optical system by removing the initial diversity function from the phase map; and repeating the process beginning with iteratively performing a phase retrieval on the intensity data using the updated estimate of the phase of the optical system in place of the initial estimate of the phase of the optical system, and using the updated diversity function in place of the initial diversity function, until a predetermined convergence is achieved.
