Abstract

The present invention relates to a large-size bionic holographic three-dimensional dynamic display method with large field of view. The method includes: a computer generated hologram (CGH) is loaded on a spatial light modulator; a large field angle is formed by changing the optical path through a microlens array or a diffractive optical element having same optical property with the microlens array disposed on a light-emitting surface of pixel structure of the spatial light modulator. Each microlens of the microlens array has one-to-one correspondence with each pixel of the pixel structure of the spatial light modulator. The cost is saved and design of the system structure is simplified while field view of the three-dimensional holographic display is expanded and large size is reappeared. The pixels in the spatial light modulator are fully utilized to avoid loss of resolution, and the display precision is provided to meet the growing demand of people.
