Abstract
The present disclosure relates to a hologram recording system that has an optical structure capable of replacing a polarization image sensor, thereby acquiring high-resolution holograms in real time by utilizing a high-resolution general image sensor. The hologram recording system for acquiring an interference pattern formed by self-interference of incident light from a target object is disclosed. The hologram recording system comprises 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. The imaging optics optically corresponds each of the plurality of polarizers to each of the plurality of pixels.

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.
