Investigation of Laser Propagation Phenomena

Abstract

The report presents a study of problems associated with using the Fourier transform restoration procedure to restore atmospherically degraded images of high flying objects. The study is divided into two parts, an examination of the restoration procedure and an estimate of atmospheric effects. The two parts were joined by choosing a model which assumes the phase front of an atmospherically degraded light wave can be represented as a truncated polynomial series. Preliminary results indicate that a point source on the bottom of an airplane is very nearly equivalent to a collimated source at the same location as far as ability to restore the degraded image of a much higher object.
