摘要:
There is provided an optical device including a plurality of polarizers that are arranged along a propagation direction of incident light, where the plurality of polarizers have transmission axes of substantially the same direction, a phaser that is provided between the plurality of polarizers, where the phaser has a retarded-phase axis forming a predetermined angle with the transmission axes of the plurality of polarizers, and a phase modulator that is provided adjacent to the phaser along the propagation direction, where the phase modulator has a retarded-phase axis of substantially the same direction as the retarded-phase axis of the phaser. Here, a phase difference generated in the incident light by the phase modulator is temporally adjusted such that the optical device transmits light in different wavelength ranges at different timings.
