System for selective irradiation with circularly polarized light

Abstract

According to the present invention, provided is a system for irradiating a target object selectively with specific circularly polarized light, comprising a polarization-state control member that controls the polarization state of light to thereby generate circularly polarized light; and a circularly polarized light-reflecting member, wherein the circularly polarized light-reflecting member is disposed at a position on which the circularly polarized light emitted from the polarization-state control member can be incident; the circularly polarized light-reflecting member generates reflected light that selectively comprises circularly polarized light of the same sense as the incident circularly polarized light from the polarization-state control member; and the circularly polarized light-reflecting member is disposed such that the target object can be irradiated with at least a part of the reflected light.
