Abstract : This report concerns the final status of the ONR contract entitled Development of an Interferometric Technique for Background Radiation at 10 micrometers. The purpose of the proposed instrument was to improve the detectability of a background limited source in the atmospheric window from 8 to 12 micrometers. Such an improvement would be possible if the photons arising from the source and background could be discriminated interferometrically such that the desired signal photons are preferentially detected. This has been the motivating idea of the devices considered.
