Phase Retrieval Algorithms for Wavefront Analysis

چکیده
This image stack serves as a data set for the iterative PR algorithm. We first compose the complex wavefront by the measured amplitude and an initial guess of phase. Then this distribution is propagated to the next plane, the amplitude is replaced by the measured one, the phase is kept. After performing this procedure repeatedly from plane to plane through the image stack the achieved complex wavefield approaches to a convergent solution [1].

متن کاملMeasurement range of phase retrieval in optical surface and wavefront metrology.
Phase retrieval employs very simple data collection hardware and iterative algorithms to determine the phase of an optical field. We have derived limitations on phase retrieval, as applied to optical surface and wavefront metrology, in terms of the speed of beam (i.e., f-number or numerical aperture) and amount of aberration using arguments based on sampling theory and geometrical optics. These...

NASA Tech Briefs, April 2007 rithms that recover optical phase information, and phase-retrieval algorithms constitute a subset of this class. In phase retrieval, one utilizes the measured response of the optical system under test to produce a phase estimate. The optical response of the system is defined as the image of a point-source object, which could be a star or a laboratory point source. T...
متن کاملDetermination of wavefront structure for a Hartmann wavefront sensor using a phase-retrieval method.
We apply a phase retrieval algorithm to the intensity pattern of a Hartmann wavefront sensor to measure with enhanced accuracy the phase structure of a Hartmann hole array. It is shown that the rms wavefront error achieved by phase reconstruction is one order of magnitude smaller than the one obtained from a typical centroid algorithm. Experimental results are consistent with a phase measuremen...
متن کاملPhase retrieval with signal bias.
The effect of a uniform measurement bias, due to background light, stray light, detector dark current, or detector offset, on phase retrieval wavefront sensing algorithms is analyzed. Simulation results indicate that the root-mean-square error of the retrieved phase can be more sensitive to an unaccounted-for signal bias than to random noise in practical scenarios. Three methods for reducing th...
