Abstract:

A two-channel infrared radiometer designed for use in satellites and space probes is described. The radiometer uses an optical chopper and correlated amplifier system. It uses lead sulfide, lead selenide, or silicon photovoltaic detectors. The minimum detectable radiance is 4 x 10 to the minus 7th power wattsq cm steradian at wavelengths of 2.2 and 2.7 microns. The radiometer has a five decade dynamic range. Author
