Three-Color Infrared Radiometer

Abstract

A three-color infrared radiometer, intended primarily for examining the thermal radiance from the sea with maximum sensitivity for small temperature differences was designed. The radiometer operates in wavelength bands matched to the three most transparent atmospheric windows in the infrared, namely 2.3, 3.8, and 10 microns. Its thermal sensitivity in the two longer-wavelength bands equals the expected mean background thermal noise level. The radiometer was developed for an experiment to detect internal ocean waves through their radiometric effects.
