Paper Abstract

First order velocity variations in the moving mirror of typical interferometer spectrometers are usually compensated for by using a HeNe laser in the system to provide an accurate path difference monitor. The second order effects due to amplitude and phase distortion in the signal train analog band pass filter can be the dominant source of noise and distortion in the spectrum and, therefore, significantly effect the overall system design. Experimental studies of the important parameters effecting this distortion have been compared to the theoretical calculations of Zachor et al.
