Title:
VOLUME HOLOGRAPHIC ELEMENT, AND MANUFACTURING METHOD AND MANUFACTURING SYSTEM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/090565
Kind Code:
A1
Abstract:
Disclosed is a volume holographic element, comprising at least one pixelate information layer and at least one substrate layer. The information layer is arranged on the substrate layer, or the information layer is arranged between two adjacent substrate layers. From the profile of the volume holographic element, the information layer has an array-distributed pixelate stripe surface. Each stripe surface in each pixel is periodic, and forms an included angle with a substrate plane. Each pixel is a reflective Bragg volume grating. A manufacturing method and manufacturing system for a pixelate reflective volume holographic element. By regulating and controlling an interference light beam, performing pixelate stitching exposure on a photosensitive layer of a volume holographic recording material, and performing subsequent chemical or physical processing, a pixelate reflective volume holographic optical element with complex optical parameters is formed.
