Abstract: A static Fourier transform spectrometer is disclosed that includes a beam splitter, a mirror device, and a collection optic. The beam splitter divides an input light beam into a first arm and a second arm, wherein the first arm is reflected by the beam splitter and the second arm passes through the beam splitter, wherein the first arm extends to the converging optical unit without deflection after reflection at the mirror device, wherein the second arm extends to the converging optical unit without deflection after passing through the beam splitter, and wherein the collection optic merges the first arm and the second arm for interference.
