The efficiency of a wave-front-dividing interferometer with circular symmetric sets of reflectors is studied and compared with that of a lamellar grating. The circular-reflector interferometer shows more efficient modulation over larger spectral regions in the far IR than the lamellar grating does. In contrast to Michelson and Martin–Puplett interferometers no beam splitters are employed.
