The theory and implementation of a postdetection turbulence compensation technique for obtaining high resolution imagery through turbulence is presented. This technique records a turbulence degraded image and an estimate of the atmospheric transfer function simultaneously. A compensated image is then produced through a digital deconvolution. The method is referred to as self-referenced speckle holography as the observed object acts as the reference source for a turbulence estimate, eliminating the requirement for an unresolved star. Low-light images generated in the laboratory, and astronomical field results obtained in February 1990 at the University of New Mexico's Capilla Peak Observatory in Manzano, New Mexico are discussed.
