Abstract

We describe here a far-infrared photometer capable of detecting simultaneously in three bands in the region 20–120 microns, each band having an array of 3 or 4 photoconductive detectors. We present and discuss its laboratory performance and the results obtained on the planet Venus during an air-borne observational programme using a 32.5 cm telescope. We also present the atmospheric spectra obtained by a Michelson interferometer aboard the aircraft.
