Phase determination of an amplitude modulated complex wavefront

Not Accessible

Your library or personal account may give you access

Abstract

An electronic–optical method is described for obtaining the phase of an arbitrary complex 2-D wavefront. The method consists of intensity detection, limiting, pulse width normalization, differentiation, dc filtering, and integration. Theoretical analyses and experimental confirmation are included. Applications of this scheme that are discussed include space variant processing, adaptive optics, data transmission, kinoforms, holography, and optical data processing.
