Abstract

A double-beam interferometer laboratory has been designed and built for use in testing a background optical suppression scheme (BOSS). The interferometer system features a 1 cm -I double-beam interferometer (2 cm beam aperture), a tailored modulation transfer function for the two beams, a servocontrolled drive for the moving retroreflecting mirror, a laser retardation reference system, PbS detector and associated electronics, a 16K fast fourier transform (FFT) analyzer, and a CRT plus X-Y plotter for displaying both interferograms and 1cm-1 spectra in real time. The laboratory facility also includes a test source that projects a point source immersed in a controllable spatial background.
