Small glints as an aid for imaging geosats using an optical Michelson interferometer

Paper Abstract

A Michelson optical interferometer, such as an upgraded version of the Navy Precision Optical Interferometer, could image geosynchronous satellites (geosats) with resolution of roughly 1 m. Baselines that sample features as small as 0.2 m can be built, however, the fringes would be swamped by the resolved component. Recent observations have shown that small glints known as “glintchen,” aside from being a nuisance, serve to isolate and highlight the signal from these structures. Imaging of geosats during glintchen events can determine the dimensions of these structures and can also play a critical role in determining if these glintchen are due to a previously undetected companion satellite. An approach for performing this glint-aided imaging of geosats and the wealth of detail it would yield, is discussed.
