Embodiment Construction
[0029] Below in conjunction with accompanying drawing, specific working process of the present invention is given description.
[0030] figure 1 It is a schematic diagram of a visual optical display device with a planar zigzag sandwich structure of the present invention. like figure 1 As shown, the system composition of the optical display device of the present invention includes: an image display light source 10 , a collimator lens group 11 , a coupling input surface 12 , a planar waveguide substrate 13 , and a sawtooth groove structure 14 . The light from the image display light source 10 is collimated by the collimating lens group 11 and then enters the coupling-in surface 12 , and enters the planar waveguide substrate 13 after being reflected by the coupling surface. After the light is transmitted without loss in the planar waveguide substrate to the position where the display output is required, since the sawtooth groove structure 14 is located at the position of the di...

The invention provides a visual optical display device of planar sawtooth sandwich structure which includes an image display light source, a collimating lens group, a coupling input surface, a planar waveguide substrate and a sawtooth groove structure. The image display light source is used for sending display optical waves for displaying needed images, the collimating lens group is used for collimating the optical waves sent by the optical source, the coupling input surface couples the collimated optical waves into planar waveguides, the planar waveguide substrate reflects and spreads the input optical waves through coupling to form total-reflection optical waves, and the sawtooth groove structure is used for view field extension and optical wave output coupling of the substrate. The visual optical display device has the advantages of being light and thin in structure, easy to expand in terms of the field angle, simple and feasible in processing technology and low in cost, and can be applied to the fields such as wearable display, real-time field operation, naked-eye 3D display and search positioning display.
Description
technical field [0001] The invention relates to a visual optical display device, in particular to a visual optical display device with a plane zigzag sandwich structure that can be used for full-eye wearable penetrating display. Background technique [0002] For head-mounted display optical systems, in order to reflect the effect of augmented reality, optical components are usually used to virtually display image information at a certain distance in front of the human eye, so that the wearer can observe the surrounding scenery while browsing the information. change so as not to affect normal behavior. For this purpose, the augmented reality wearable display optical system usually requires the display system to have the characteristics of large field of view, light and thin structure, and augmented reality in order to enable the wearer to obtain all the information from the display light source in time. The traditional head-mounted display system is based on a 45º reflective...
