S/N ENHANCEMENT OF AN FTS SYSTEM BY DYNAMIC FILTER COMPENSATION FOR SAMPLING ERRORS
MetadataShow full item record
Publisher:Ohio State University
The S/N capability of an idea lab Fourier Transform Spectrometer using a JgCdTe detector was improved by a factor of 30 to a level where system performance with a Nernst glower source was limited only by the extrinsic detector noise. The results reported here constitute a hardware demonstration of an analysis recently published by Zachor and Aaronson. Our analysis and hardware demonstation are in substantial agreement with the work of Zachor and Aaronson which was carried out independently. Diagnostic date will be presented which illustrate the distortion to the spectrum caused by errors in sampling. The characteristics/specifications for signal and sampling control electronics which provide dynamic compensation for sampling errors will be discussed, and test date showing the 30 fold improvement in S/N will be presented.
