Paper Abstract

Fourier Telescopy is an active laser-based imaging technique based on an aperture synthesis similar to long baseline interferometry. The FT method will potentially allow high- resolution images of objects in Geosynchronous (GEO) orbit. A full-scale system to implement the FT method is being built by TREX Enterprises as part of the Air Force Research Laboratory's Geo Light Imaging National Testbed (GLINT) program. An end-to-end computer simulation has been developed to determine the effects of atmospheric turbulence and beam jitter on the quality of the reconstructed image. We discuss the functions of the simulation code, and present sample results for image quality of the GEO object model. Simulations confirm that the GLINT system is relatively insensitive to atmospheric effects, as long as the seeing is at least moderately good and consistent with current data taken in souther New Mexico.
