摘要： PROBLEM TO BE SOLVED: To solve the problem that diffraction efficiency to natural polarization or the like is deteriorated since diffraction efficiency characteristics between S polarization and P polarization are deviated in accordance with a fact that a Bragg angle becomes larger in a transmission type VPH (volume Phase Holographic) diffraction grating and a thick transmission type rectangular diffraction grating.SOLUTION: It becomes possible to set diffraction efficiency of S polarization and P polarization to desired spectral characteristics in arbitrary wavelength and an arbitrary Bragg angle by making two values: difference between the maximum refractive index and the minimum refractive index to the S polarization; and difference between the maximum refractive index and the minimum refractive index to the P polarization to different predetermined values, by using an optical anisotropic medium as a material of a transmission type VPH diffraction grating and a thick transmission type rectangular diffraction grating.

摘要： PROBLEM TO BE SOLVED: To provide a multiple image polarization element which has a polarization characteristic suitable for an optical apparatus.
SOLUTION: Two or more multiple image polarization elements are produced by choosing two or more different birefringence crystals among LiNbO
3 , calcite, YVO
4 or the like and wavelength dependency of an isolating angle or isolating breadth can be adjusted by combination of the multiple image polarization elements. Since the isolating angle at a short wavelength side can be made small or the isolating angle or the isolating breadth can be linearly changed from a short wavelength region toward a long wavelength region, when the multiple image polarization element is used for a polarization imaging apparatus, a polarization spectroscope and a multi-channel Fourier spectroscope, a wide wavelength range can be simultaneously measured.

摘要翻译：解决的问题：提供具有适合于光学装置的偏振特性的多重图像偏振元件。解决方案：通过在LiNbO 3 SB 3，方解石，YVO SB 3等中选择两种或更多种不同的双折射晶体和波长依赖性来产生两个或多个多个图像偏振元件可以通过多个图像偏振元件的组合来调节隔离角度或隔离宽度。由于可以使短波长侧的隔离角小，或者隔离角度或隔离宽度可以从短波长区域向长波长区域线性变化，所以当将多像偏振元件用于偏振成像装置时，可以同时测量宽波长范围的偏振光谱仪和多通道傅里叶分光镜。版权所有（C）2010，JPO＆INPIT
