Abstract
A terahertz spectroscopic apparatus includes a polarization beam splitter transmitting or reflecting a linearly polarized terahertz wave, a quarter wave plate imparting a phase difference of 90° to a terahertz wave impinging thereon, and an optical member guiding a circularly polarized terahertz wave impinging thereon from the polarization beam splitter via the quarter wave plate to an irradiation surface.
