The dentiform embedded planar waveguide optical device has characteristics of being simple in processing process, easy to realize, light in weight, compact in structure, flexible in vision field increase and high in optical wave coupling efficiency, not only can be used for wearable display, but also can be used for the application fields such as extension uniform illumination, naked eye 3D display and mobile screen display.

Description

technical field [0001] The invention relates to a planar waveguide optical device, in particular to a tooth-shaped mosaic planar waveguide optical device which can be used for full-eye wearable penetrating display. Background technique [0002] The traditional helmet-mounted display system is implemented with a 45º reflective structure. This structure has a great contradiction between the increase of the field of view and the overall weight of the helmet. In order to increase the field of view, it can only be achieved by increasing the area of ​​the 45º reflective surface, which means that the weight of the overall reflective system increases. Usually, the helmet-mounted display device uses optical components to virtually display image information at a certain distance in front of the human eye in order to facilitate the wearer to browse information without affecting the normal behavior. The core component of this type of optical display system consists of three parts: gra...
