Title:
WIDE-FIELD AND LARGE-SIZE BIONIC HOLOGRAPHIC THREE-DIMENSIONAL DYNAMIC DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2018/095421
Kind Code:
A1
Abstract:
A wide-field and large-size bionic holographic three-dimensional dynamic display method, comprising: loading on a spatial light modulator (1) a calculation hologram generated in real time; and changing a light path to form a large field angle by means of a micro-lens array (3) arranged on a light-emergent surface of a pixel structure of the spatial light modulator (1) or a diffractive optical element (4) having the same optical characteristics as the micro-lens array (3), wherein each micro-lens in the micro-lens array (3) corresponds to each pixel point (2) of the pixel structure of the spatial light modulator (1) on a one-to-one basis. A field angle for three-dimensional holographic display is enlarged while saving costs and simplifying the design of a system structure, thereby realising reproduction in a large size. Moreover, due to the optimisation of the system structure, pixels on the spatial light modulator (1) can be fully used, thereby avoiding the loss of resolution, and a higher display fineness is provided at the same time, thereby satisfying the increasing demands of people.
