Title:
OPTICAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/222302
Kind Code:
A1
Abstract:
An optical system, comprising: a wavefront modulation element (500) having a first surface and a second surface opposite each other, wherein the first surface of the wavefront modulation element (500) is used for receiving a first light wave that does not have a complete planar wavefront, and the second surface of the wavefront modulation element (500) is used for emitting a second light wave that has a complete planar wavefront, which is formed by beam shaping of the first light wave by the wavefront modulation element (500). The size constraint of each element of the optical system can be reduced, in addition, it is ensured that the quality of a target image is not reduced.
