Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The object of the present invention is to provide a kind of based on aspherical variable focal length AR glasses, can be suitable for myopia population.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Fig. 1 is the embodiment of the present invention based on aspherical variable focal length AR glasses guide structure schematic diagram, as shown in Figure 1,
It is provided by the invention based on aspherical variable focal length AR glasses include display light source 1, collimation lens 2, planar-light guide 4, in
The heart is in the spill light guide 8 and connection lens 5 of concave shape；Connection lens 5 are recessed for connecting planar-light guide 4 and spill light guide 8
Shape light guide 8 is process by planar-light guide.
Planar-light guide 4 is formed by two light guide gluings, and glued plane is inclined-plane, and posts semi-transparent semi-reflecting film, by planar light
It leads the glued plane in 4 and is denoted as the first glued plane 3；First glued plane 3 is mirror reflection surface, can be provided for planar-light guide
One has the visual field of uniform luminance, and the tilt angle setting of the first glued plane 3 can be in planar light after its reflection with light
Middle total reflection propagation is led to be configured for standard.
Spill light guide 8 is formed by multiple light guide gluings, and glued plane is inclined-plane, and posts semi-transparent semi-reflecting film, by spill light
It leads the glued plane in 8 and is denoted as the second glued plane 7, the second glued plane 7 is located at the central concave of spill light guide 8；Spill
Light guide 8 can be such that light focuses.
Lens 5 are connected, inside offers skewed slot, as shown in Fig. 2, being sealed with liquid in skewed slot, skewed slot is denoted as adjustable folding
Penetrate face 6；
The glued plane 3 of the light that display light source 1 issues directive first after the collimation of collimation lens 2, through the first gluing
Plane 3 carries out total reflection transmission after reflecting in planar-light guide 4, after planar-light guide 4, directive is adjustable plane of refraction 6, through adjustable
After plane of refraction 6 reflects, into spill light guide 8, the glued plane 7 of directive second after the total reflection of spill light guide 8 transmission, through second
It is emitted after the reflection of glued plane 7.
