AN INVESTIGATION OF THE OPTIMIZATION OF PARAMETERS AFFECT^ INC THE IMPLEMENTATION OF FOURIER TRANSFORM SPECTROSCOPY AT 20-500 μ FROM THE C 441 AIRBORNE INFRARED OBSERVATORY

摘要

At the present time, a program for 20-500 micron spectroscopy from the NASA flying CI 41 infrared observatory is being carried cut with a Michelson interferometer. It is the purpose of this report to study the parameters affecting the performance of the instrument and to recommend the optimal configuration for high performance on the C-141 aircraft. As each parameter is dis¬cussed the relative merits of the two modes of mirror motion (rapid scan or step and integrate) will be presented.
