Abstract
A target is illuminated through an optically distorting region, such as atmospheric turbulence or non-precision optics, by coherent light and a first set of data is recorded indicative of the complex amplitude of scattered radiation and such target is thereafter illuminated by incoherent light to produce a second set of data indicative of the nature of the region; the second set is divided into the first set, and the resulting data is Fourier-transformed to produce a diffraction-limited target image.
