Paper Abstract

This paper will briefly review techniques that allow phase errors that are inherent in multiple- aperture receivers or due to atmospheric turbulence in large single-aperture systems to be compensated and thus allow nearly diffraction-limited imaging at optical frequencies from such high aberrated structures. Attention will b given to the effects of using different types of arrays, the type of detection used, and the nature of the received signal. Emphasis will be place upon real-time operation but iterative post-image formation techniques such as maximum entropy and blind deconvolution will also be mentioned. A brief discussion of the hardware/technology required for optical phased arrays will be given.
