Paper Abstract

Two sharpness functions are considered for the problem of dynamic phase estimation and correction of aberrated images. One is based on the integral of the square of the image irradiance distribution. The other uses integration of the irradiance distribution over an area smaller than the diffraction-limited resolution area. Examples of phase retrieval using these sharpness functions are given, and laboratory experiments on their verification are described. Applications of this technique to high-energy laser systems, thermal blooming, imaging through atmospheric turbulence, and large optical systems are discussed.
