Abstract : A technique for performing double-beaming in Fourier spectroscopy which is capable, in a single output, of measuring the spectra of desired radiation while suppressing the spectra of unwanted radiation. This technique is accomplished by feeding a pair of input beams on opposite faces of a beamsplitter at a preselected location thereon. In this manner radiation which is common to both input beams will be suppressed in the output interferogram. (Author)
