Measurements of the Atmospheric Background Emission Between 10μ and 100 μfrared astronomy programme at University College London. The instrument used was a Michelson interferometer, flown at night on a balloon from Palestine, Texas during August 1969. Details of the instrument and the methods of data reduction and calibration are given elsewhere .

Performance Tests of InSb and Ge Bolometersd that under these conditions the performance of the InSb detector is better by a factor of ∼25. The indium antimonide detector has been used in the laboratory for high resolution spectroscopy using the polarizing interferometer described by Martin and Puplett .
