The present invention provides a polarizing camera device whose mechanical operation part is unnecessary and can be measured by snapshot polarizing imaging, especially for the alignment of high-precision positions of polarizing elements is unnecessary, especially in particular In terms of cost, it is also a low-cost polarized camera. The present invention provides a polarized imaging device having an anisotropic diffractive lattice element, a lens element, and a light-receiving element whose optical anisotropy is periodically adjusted. |
