Paper Abstract

Various schemes have been investigated that facilitate the imaging of objects viewed through time-varying scattering elements such as the atmosphere. Analyses we have performed in connection with enhanced-backscatter imaging and a particular class of superresolving imaging systems have led to a general principle that describes the transfer of the coherence properties of a wavefield that passes twice (double-passage) through a dynamic scatterer. Restoration of the coherence properties of the wave allow the formation of images with light that has been doubly scattered. Analyses are presented for the enhanced-backscatter, superresolution, and general case, and brief remarks presented regarding the possible application of the principle to remote image formation through the turbulent atmospheric.
