Liquid crystal polarization camera system based on microlens array

The invention discloses a liquid crystal polarization camera system based on a microlens array. The system comprises a micro-lens array, a liquid crystal polarizing film and an image sensor, the micro-lens array and the liquid crystal polarizing film are relatively arranged in parallel, the micro-lens array comprises a plurality of micro-lens units which are regularly arranged, each micro-lens unit corresponds to each focal plane unit on the liquid crystal polarizing film, light is split into multiple beams of light after entering the micro-lens array, and the multiple beams of light are transmitted to the liquid crystal polarizing film. Light beams penetrate through the liquid crystal polarizing films and are respectively focused on the image sensor, the light beams penetrate through the micro-lens array to be split and focused on the corresponding liquid crystal polarizing films, the liquid crystal polarizing films are filtered in four-angle polarization directions, polarization units of the four angles ser
