Title:
POLARIZATION IMAGE CAPTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/039486
Kind Code:
A1
Abstract:
The present invention provides a polarization image capturing device with which polarization image measurement in a snapshot is possible, without the need for a mechanical operating unit, in particular a polarization image capturing device which does not require high precision positioning of a polarizing element, and more particularly a polarization image capturing device which, in terms of cost, is relatively inexpensive. The present invention provides a polarization image capturing device including an anisotropic diffraction grating element having periodically modulated optical anisotropy, a lens element, and a light receiving element.
