Diffraction-limited imaging through a phase-distorting medium
Abstract
An achromatic method of seeing through a phase-distorting medium, such as a turbulent atmosphere, utilizes a grating interferometer. Measurements are at sample points throughout the region of fringe formation. A set of nonlinear simultaneous equations is generated and then solved by computer.
