1. A hologram recording system acquiring an interference pattern formed by self-interference of incident light from a target object and comprising:
a geometric phase lens converting the incident light into left-circular polarization and right-circular polarization;
a polarizer array including a plurality of polarizers;
an image sensor including a plurality of pixels; and
an imaging optics disposed between the polarizer array and the image sensor,
wherein the imaging optics optically corresponds each of the plurality of polarizers to a corresponding one of the plurality of pixels.
