Abstract: A depolarizer includes a pair of wedge-shaped plates made of an optically isotropic material, laid one on top of another such that the total thickness is constant and wedge-plate holding means for holding the pair of wedge plates separately. The wedge-plate holding means includes a pressure-applying section for applying pressure to each of the pair of wedge plates in a direction perpendicular to the thickness direction of the pair of wedge plates. The pressure-applying direction for one of the pair of wedge plates and the pressure-applying direction for the other of the pair of wedge plates intersect at an angle of 45 degrees.

Abstract: An object identification device includes an image capturing device to capture images polarized in different directions. A noise removal unit removes noise in the polarized images using a noise removing parameter. An index value computing unit computes an object identification index value for identification-processing areas in the polarized images using data of noise-removed polarized images. An object identification processing unit conducts object identification by determining identification processing areas corresponding to an identification target object based on the object identification index value. An environment information obtaining unit obtains environment information. An environmental condition determination unit determines an environmental condition based on the environment information. A parameter storage unit stores noise removing parameters prepared for mutually exclusive environmental conditions. The noise removal unit reads a noise removing parameter from the parameter storage unit to conduct noise removal. A method of identifying an object and a spectroscopic image capturing apparatus are also provided.

Abstract: A tunable optical spectrometer is disclosed that includes a medium configured to perform polarization rotation within a frequency band on a linearly polarized test beam, wherein the medium is circularly birefringent, and wherein the polarization rotation is achieved based on two-photon-absorption. The medium includes a gaseous substance, a reference laser beam of circular polarization and a longitudinal magnetic field. The test beam propagates through the medium twice, once in the same direction as the magnetic field, and once in the opposite direction of the magnetic field. The test beam undergoes polarization rotation an amount that depends upon the frequency of the test beam.
