Embodiment Construction

[0021] Below in conjunction with accompanying drawing, specific working process of the present invention is given description.

[0022] figure 1 It is a schematic diagram of the tooth-shaped inlaid planar waveguide optical device of the present invention, such as figure 1 As shown, the system composition of the optical device of the present invention includes: a display light source 10 , a collimator lens 11 , a coupling input surface 12 , a planar waveguide substrate 13 , and a micro-toothed structure 14 . The light wave emitted by a point on the display light source 10 is collimated by the collimating lens 11 and then incident on the coupling input surface 12, and then propagates into the planar waveguide substrate 13 after being reflected by the coupling surface, and the light wave is totally reflected in the planar waveguide substrate After a certain optical distance, the form reaches the micro-toothed structure 14, which breaks the total reflection condition and couple...

Abstract

The invention provides a dentiform embedded planar waveguide optical device which comprises an image light source, a collimating lens, a coupling input surface, a planar waveguide substrate and a micro dentiform structure, wherein the image light source is used for emitting display optical waves for displaying a required image, the collimating lens is used for collimating the optical waves emitted by the light source, the coupling input surface is used for coupling the collimated optical waves into a planar waveguide, the planar waveguide substrate is used for performing reflecting propagating on the coupled optical waves to form total reflection optical waves, and the micro dentiform structure is used for outputting the total reflection optical waves in a coupled manner. 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 45° 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: g...
