Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Before the technical scheme in introducing the embodiment of the present invention, the technical principle of laser scanning imaging is first introduced,
Fig. 1 is refer to, Fig. 1 is the schematic diagram of laser scanning retina image-forming, as shown in figure 1,101 be laser generator, 102 be two dimension
Scanning means, 103 be the retina of human eye.
For convenience of introduction, so that the resolution ratio of the image of imaging is 5*5 as an example, in the current direction alignment of two-dimensional scanner
During the pixel of white, laser generator sends the laser of white, and is deflected by two-dimensional scanner and reflex to the pixel
Point, that is, realize the scanning to the pixel；In next position of two-dimensional scanner, if the direction pair of two-dimensional scanner
During the pixel of quasi- black, laser generator sends the laser of corresponding black, is deflected and reflexed to by two-dimensional scanner
The pixel, or do not send laser, that is, the scanning to the pixel is realized, by that analogy, i.e., can realize whole image
Scanning, so, pass through the visual persistence phenomenon of human eye, it becomes possible to a width is showed on the retina of human eye and is completely schemed
Picture, as shown in figure 1, can finally form a Chinese character " king " in human eye.In actual applications, sent by laser generator
The laser of different colours, such as the laser of different colours can be sent by way of coupling multiple one-wavelength lasers, and it is complete
Site preparation scans image to be shown, so as to form colourful image in human eye, just repeats no more herein.
It should be noted that the laser of black refers to the corresponding encoded radio under default color coding pattern, for example,
Under RGB color pattern, the rgb value of black is (0,0,0).
Fig. 2 is refer to, Fig. 2 is the structural representation for the near-eye display system that the present embodiment provides, as shown in figure 1, this is near
Eye display system includes light source 201, beam spread array 202, mirror scanner part array 203 and horizontal extension waveguide 204, instead
Penetrating scanning device array 203 includes multiple mirror scanner parts；
The light that light source 201 is sent is extended to multiple light beams after beam spread array 202, multiple light beams respectively by
Multiple mirror scanner parts are scanned and reflex to horizontal extension waveguide 204, then are transferred to people by horizontal extension waveguide 204
Eye.
Horizontal extension waveguide can set multiple imaging minute surfaces in horizontal fiber waveguide, such as can be in multiple horizon lights
Plated in waveguide can anti-permeable membrane layer and glued together, can anti-permeable membrane layer form an imaging minute surface, light is entering
Be transferred to after horizontal fiber waveguide this can anti-permeable membrane layer when, a part of light can reflect at this on anti-permeable membrane layer, from
And be transferred to human eye, another part light can transmitted through can anti-permeable membrane layer to it is next can anti-permeable membrane layer, by that analogy, so as to
The effect for the exit pupil diameter for expanding near-eye display system can be realized.
Certainly, in order to ensure the uniformity of luminous intensity, can according to actual conditions set each can anti-permeable membrane layer it is anti-
Efficiency is penetrated, for example, so that horizontal extension waveguide includes 5 imaging minute surfaces as an example, according to transmission of the light in horizontal extension waveguide
Direction, the reflectivity of the 1st minute surface can be arranged to 20%, the reflectivity of the 2nd minute surface is arranged to 25%, by the 3rd
The reflectivity of minute surface is arranged to 33%, and the reflectivity of the 4th minute surface is arranged into 50%, and the reflectivity of the 5th minute surface is set
For 100%, so, the luminous intensity of each minute surface outgoing is the 20% of total light intensity degree, is just repeated no more herein.
As can be seen that due to the light that light source 201 is sent is expanded into multiple light beams by beam spread array 202, then
It is scanned by mirror scanner part array 203 and reflexes to horizontal extension waveguide 204, then again will by horizontal extension waveguide 204
Multiple light beams are transferred to human eye, so, the exit pupil diameter of near-eye display system are expanded by horizontal extension waveguide 204 so that
Near-eye display system output light can bigger scope it is enterprising enter eyes pupil in, so with single optical lens
Emergent pupil is compared, and the emergent pupil that this programme provides significantly increases, so as to reduce or avoid the strict limit to the position of eye-observation
System, and then the applicable crowd of virtual reality device or augmented reality equipment is expanded, and without user to virtual reality device
Or augmented reality equipment carries out interpupillary distance regulation, user is it also avoid because regulation result inaccurately leads to not obtain well virtual
The defects of experience of reality or augmented reality are experienced.
