Abstract

A spectrometer includes a beam splitter that receives incident light rays and splits each of the incident light rays into first and second spatially displaced, linearly polarized light rays that respectively have first and second polarization directions orthogonal to each other; an optical member that receives the split incident light rays from the beam splitter and optically converts the split incident light rays into a plurality of light beams that are respectively guided to mutually differing locations so as to generate interference fringes in the respective locations, each of the plurality of light beams including a component of the first linearly polarized light rays and a component of the second linearly polarized light rays; and a detector that detects the interference fringes respectively generated by the plurality of light beams.
