Upper atmospheric studies using remote infrared sensing
Abstract
A history of Michelson interferometry, theory, applications, increasing resolution, and subsequent invention of Michelson interferometry spectrometry is presented. Aircraft borne spectrometers have needed tilt and backlash avoidance, and it is noted that improvements now limit mirror translation to an arcsec. The use of a linear variable differential transform sensor for servomechanism feedback control, cryogenic cooling for readings in the 2-5.6 micron region together with a piston mirror transport mechanism, and interfaces with data storage units for later transmission is described. Finally, the development of wide angle interferometer spectrometers for studying low brightness upper atmospheric emissions is reviewed.
