Paper Abstract

Measuring optical wave-fronts precisely is a difficult task because detectors directly sense intensity, not phase. The most common method of measuring the phase uses an interferometer that creates an intensity distribution from which the phase of the field can be determined more easily. In order to overcome the wave-front distortion caused by atmosphere turbulence and optical system aberration, the system of wave-front solutions based on the focal plane image information can be used in the optical system in-line detection. The realizations of phase solver technology mainly include phase diversity and phase retrieval. So, this paper mainly explains phase diversity and phase retrieval.
