Abstract

The present disclosure provides an optical device, comprising a light source for generating light including first polarized light of a first phase; an adjustment structure for changing a propagation path of the light; wherein the adjustment structure includes A polarization beam splitting structure, the polarization beam splitting structure is used to reflect the first polarized light.

Description

technical field [0001] The present disclosure relates to an optical device. Background technique [0002] With the rapid development of electronic technology, various devices are increasingly used in many scenarios such as life and work. For example, more and more optical devices are used in many scenarios, among which, for example, head-mounted display devices can be used to generate images and provide them for viewing by users. However, the existing optical equipment has low optical conversion efficiency from image generation to image incident to the user's eyes, and the privacy of the generated image is low, so that others other than the user using the device can view the generated image. [0003] Therefore, how to improve the optical efficiency and privacy of optical devices has become an urgent problem to be solved. Contents of the invention [0004] One aspect of the present disclosure provides an optical device including a light source and an adjustment structure....
