Analytical Studies of Phase Estimation Techniques. Volume 1
Abstract
The phase retrieval problem consists of the wave aberration function of an optical system from intensity measurements made in the image plane. An adaptive optical system may then be corrected for the aberration to yield improved performance. Several algorithms for performing phase retrieval are discussed and the results of computer simulations are presented. The sensitivity of the algorithms with respect to type and magnitude of aberrations, image plane detector dimensions and noise levels, non-monochromaticity of incident radiation and the structured target objects is investigated. Results demonstrate the practicality of phase retrieval.
