Abstract

Rapid scanning of Fourier Transform Spectrometers (FTS) has become the norm for most commercial and military FTS systems. Optimization of scan (retardation) rates is normally predicated on detector response time, recording limitations and mechanical factors. This approach will not necessarily lead to optimum performance when additional sources of noise are included in the total error budget. Examples of such sources of noise are amplitude and phase modulation errors as well as dynamic range limitations in the recording process and truncation errors in the transform process. All these sources of noise are subject to what is sometimes called, ironically, "Fellgett's disadvantage" and that their magnitude depends on the integrated intensity of the source. The effect of these noise sources and techniques to minimize them will be discussed with relevance to some practical and real situations.
