13. An optical image capturing device comprising:
an aperture diaphragm (AD);
an optical element block comprising a front surface facing an object on which the AD is disposed and a back surface facing an image plane, the optical element block being optically coupled with the AD; and
a sensor configured to be optically coupled with the optical element block and sense the image plane,
wherein the optical element block comprises at least one lens element, a wire grid polarizer (WGP), a quarter wave plate (QWP), and a cholesteric liquid crystal (ChLC) layer, and
wherein the WGP, the at least one lens element, the QWP, and the ChLC layer are disposed to provide a predetermined multi-transmission of light from an object side to the image plane.
