Title:
OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/060339
Kind Code:
A1
Abstract:
An optical device (1) is provided with a light input/output unit (10), a transmissive diffraction grating (21), a lens (30) and a mirror array (40). The grating in the transmissive diffraction grating (21) is formed so as to extend in the x-axis direction at a constant frequency, and the transmissive diffraction grating (21) performs wavelength division on the light inputted into the input port, and outputs the same. The transmissive diffraction grating (21) is rotatable around a prescribed axis. The transmissive diffraction grating (21) outputs light of each wavelength orthogonally from the rotation axis and in a direction according to the wavelength. The lens (30) concentrates the light of each wavelength that has been divided and outputted by the transmissive diffraction grating (21) to different positions from one another.
