Reflective optical system for a hemispherical-field radiometer
Abstract
The Radiation Measurement System (RAMS) is a project at NASA Ames Research Center to develop infrared radiometers for use in studying radiative transfer within the earth's atmosphere. These radiometers will use a liquid nitrogen cooled reference source and thermal stabilization of the optics. One of the radiometer designs calls for a hemispherical field of view, which has stimulated development of a new optical system. The system developed uses Winston cones, some of them in the reverse of the usual direction. This optical system has been optimized for the RAMS project needs and simulated on a computer for verification.
