29 October 1979 Background Suppression And Spectral Detection Using Double-Beam Interferometry: Measurements
Author Affiliations +
A series of laboratory measurements made with a double-beam interferometer having tailored modulation transfer functions is presented. These measurements demonstrate the capability of this instrument to detect faint point sources in the presence of a structured background on the basis of spatial frequency differences and/or spectral differences between the source and the background. Measurements are presented which indicate that this detection process can be carried out at a level of spectral resolution of 1 cm-1 or better.
