An AFGL interferometer used in airborne work is described in terms of the mechanisms utilized to counteract the influences of the harsh aircraft cabin environment. The problems of vibration are dealt with by reliance upon a command voltage-slaved balanced servo drive and Bendix Corp. Flexure Pivots for the moving mirror transport system. A piezoelectric crystal system maintains auto alignment of the stationary mirror thereby countering the warping effects that arise from aircraft cabin temperature fluctuations. The entire interferometer is further isolated from vibration by suspending it within an outer case on Aeroflex Corp. flexible cable mounts. The result is an instrument that delivers highly accurate and reliable data.
