SIRAS, The Spaceborne Infrared Atmospheric Sounder: an approach to next-generation infrared spectrometers for Earth remote sensing

摘要

The Spaceborne Infrared Atmospheric Sounder (SIRAS) represents a new approach to imaging spectrometry in the infrared by combining next generation wide field of view refractive/diffractive optics with high-dispersion gratings to minimize size and mass while improving spatial resolution. Prototype hardware was developed and tested on this program to demonstrate that high spectral and spatial resolution could be achieved in a package of small size and mass. The performance, development, fabrication and testing of the prototype spectrometer are discussed generally as well as potential applications for future missions. This effort was sponsored under the NASA Instrument Incubator Program (IIP).
