title: Infrared heterodyne solar radiometry.
abstract: An infrared heterodyne radiometer has sufficient sensitivity for application to high resolution spectrometric studies of the sun and the absorption of sunlight in the atmosphere. In the 10-microm region, the resolution can typically range from less than 6.7 x 10(-3)cm(-1) to 6.7 x 10(-2) cm(-1). The minimum detectable signal can approach 10(-24) W/Hz. The infrared heterodyne radiometer (IHR) can also be used for atmospheric propagation studies at the emission frequencies of the CO(2) laser for the examination of the feasibility of space-to-ground laser communication links.
