A compact reflection Fourier-transform spectrometer without moving parts is developed. The spectrometer consists of two spherical reflectors: a Sagnac interferometer and a linear detector. The developed system is as small as 202 mm long × 185 mm wide × 100 mm high. The optics and the system configuration are described, and the preliminary experimental results are shown.
