We propose a novel spectro-polarization modulator which generates radial liner polarized light sorted along wavelength concentrically. It consists of a polarizer, a retarder with high order retardation, and a quarter wave plate. If we set the radial polarizer after the spectro-polarization modulator, we can observe spectroscopic color concentrically. A displacement measurement method is proposed using chromatic aberration method.
