Background Optical Suppression System (BOSS),
Abstract
A background optical suppression scheme utilizing a double-beam interferometer-spectrometer with coaligned beams and tailored modulation, transfer functions is presented. The system is designed to enhance the detectability of localized sources in the presence of strong spatially structured background in the IR region of the spectrum. The principles of the double-beam interferometer, several different schemes for tailoring the system MTF, and the results of calculations of the signal-to-noise for a variety of MTFs and types of backgrounds, are discussed. The optical, mechanical and electrical components of the Visidyne laboratory double-beam interferometer are described . The data system and laboratory test source are also discussed. Laboratory measurements demonstrating the spatial and spectral filtering capabilities are presented. (Author)
