The present invention provides a polarization imaging device that can perform polarization imaging measurement using a snapshot without requiring a mechanical working part, particularly a polarization imaging device that does not require high-precision alignment of polarizing elements, and more particularly, a polarization imaging device that is also inexpensive in terms of cost . The present invention provides a polarization imaging device including an anisotropic diffraction grating element whose optical anisotropy is periodically modulated, a lens element, and a light receiving element. |
