Abstract

Michelson interferometers used in airborne measurements of infrared emissions are described in the context of their mechanical and electromechanical characteristics. Methods of coping with the harsh aircraft environment of high vibration and unstable cabin tempera-tures are described. The use of position sensing servo drives, flexure pivots in the moving mirror transport system, and piezoelectric crystal auto-alignment of stationary mirrors is also described. The newest interferometer to be placed in service is described with regard to its sliding piston mirror drive and associated electronic control systems. This instrument has already provided promising spectra with 0.125 cm^-1 resolution.
