Specific embodiment
It is more than that the citing to technical solution of the present invention describes the restriction it is impossible to as the scope of the present invention in detail.
Embodiment 1：Augmented reality near-eye display system as Figure 1-4, specifically, it be a binocular enhancing existing
Real near-eye display system, it includes two pieces of 1, two pieces of reflection of polarization pieces 2 of display screen that can send polarized light and one piece of concave-concave reflection
Mirror 3a.Display screen 1 is used for building the virtual image, and two pieces of reflection of polarization pieces 2 are used for processing light transmission and reflection, and concave-concave reflecting mirror 3a is used for
Reflection.Above-mentioned reflection of polarization piece 2 is mainly made up of reflection of polarization film 20, anti-reflection film 22, planar substrates 2a, wherein planar substrates 2a
In centre, in near-eye side, anti-reflection film 22 is in not easily seen side for reflection of polarization film 20.This structure has taken into full account at the delustring of veiling glare
Reason, can also do certain delustring screw thread etc. simultaneously and process in frame for movement, you can reach very perfect imaging effect.
Reflection of polarization piece 2 therein is that positive and negative only passes through polarization direction with itself direction identical light, and reflection is with itself
The reflection of polarization piece 2 of the vertical light in polarization direction；Or, the simultaneously reflection of polarization piece 2 of reflection and another side transmission, and polarize
Reflector plate 2 one side reflection is with the vertical light in itself polarization direction, the light of another side transmission any direction.Above-mentioned reflection of polarization piece
2 one sides are applied to the nearly eye face of augmented reality visual system, and another side is applied to the not easily seen face of augmented reality visual system.
As shown in figure 1, the far and near direction that our definition are located at eye vision dead ahead is defined as axial direction A, positioned at nearly eye
Region is defined as in circumferential direction B around axial direction.As shown in figure 1, this definition is mainly for simple eye definition.
For the augmented reality near-eye display system of binocular, two pieces of reflection of polarization pieces 2 are oblique respectively to be correspondingly arranged at
The front side of binocular.Because symmetrical, according to every soon, although reflection of polarization piece 2 is obliquely installed, axial direction A is substantially through at
Reflection of polarization piece 2 center.And concave-concave reflecting mirror 3a is located at and is erected in the middle of binocular, two pieces of display screens 1 are located at a left side for binocular respectively
Outside right two.The not easily seen face of the corresponding reflection of polarization piece 2 of the display surface of display screen 1, the corresponding polarization of bi-concave reflecting mirror 3a reflecting surface
The nearly eye face of reflector plate 2；Both the far-end of two pieces of reflection of polarization pieces 2 was close in the middle of binocular, and the near-end of two pieces of reflection of polarization pieces 2 divides
Outside not two about binocular.
The axial distal region of reflection of polarization piece 2 is outdoor scene 5 environment, and reflection of polarization piece 2 proximal region is nearly Vitrea eye domain.Certainly
Now and reflection of polarization piece 2 is necessarily located between concave mirror 3 and display screen 1.
Above-mentioned circumferential direction B is around axial direction, is briefly the front, rear, left and right region of nearly eye outside.
As the present embodiment display screen 1 just two about binocular outside.The definition of axial direction A is for simple eye, therefore concave-concave
The right side being equivalent to positioned at left eye of face reflecting mirror 3a, both centres of two.
" mesh " and " eye " implication in above-mentioned binocular is identical.
Concrete paths form：
Virtual optical part：The light that display screen 1 screen sends reaches bi-concave reflecting mirror 3a mono- after passing through reflection of polarization piece 2
Face, bi-concave reflecting mirror 3a reflects light back into through reflection of polarization piece 2, because the polarizability of this light is with reflection of polarization piece 2
Polarizability vertical, after reflection, essentially all of light all can enter human eye 4, greatly improves the utilization rate of screen light；
Wherein bi-concave reflecting mirror 3a act as increase virtual image distance, make virtual image ＞ outside the human eye distance of distinct vision
25.4cm, such people is more comfortable soon, and otherwise human eye does not see the content of display on Chu's screen at all；It is mainly subject to surface bent
Rate affects, and through analog information, as the radius of curvature R=125mm of the reflecting surface of bi-concave reflecting mirror 3a, the virtual image is just in human eye
At the distance of distinct vision, concrete radius can be designed as requested.And reflection of polarization piece 2 act as the light of screen is reflected into
Enter human eye.
In general, R is between 90mm-150mm, apart from relatively good.
Real light path：The light of reality scene 5 is directly entered human eye 4 through the not easily seen face of reflection of polarization piece 2, greatly improves
Transmitance.
The reflection of polarization piece 2 of the present invention is different from existing common polaroid；Common polaroid is to inclined different from itself
The light of state of shaking is absorbed, and the reflection of polarization piece 2 in the present invention have will differ from polarization state itself polarized light anti-
It is shot out.When light is incident from the negative, transmitance is higher, does not show reflection of polarization feature；When perpendicular to this polaroid polarization
When front is incident, this light can be reflected away the polarized light of state by this polaroid, has made this reflection of polarization using this feature
Piece 2 is only required for the present invention.Reflection of polarization piece has following requirement：When light is incident from not easily seen face, transmitance meets and requires：T
>=60%；When the incidence of nearly eye face, reflectance meets：F >=60%.
As shown in figure 4, the above-mentioned reflection of polarization piece 2 of the present invention is mainly by reflection of polarization film 20, anti-reflection film 22, planar substrates
2a forms, and its maximum advantage is：On the premise of ensureing big angle of visual field high-resolution, high-energy utilization rate, have ultralow
Cost advantage.The augmented reality near-eye display system that AR glasses on the market are adopted now, main cost is limited to eyeglass
Price, either waveguide piece or free surface lens, its cost of manufacture is high；What the present invention used is all extremely cheap
Raw material：Planar substrates more loosely select, as long as transmitance reaches requirement, surface accuracy reaches requirement and can use；Anti-reflection
Film 22 and reflection of polarization film 20 all select the mode of direct pad pasting, are pasted above planar substrates 2a；And the present invention's is double
Recessed reflecting mirror 3a is then completed using resin injection but is not limited to resin, and any optical plastic or optical glass all can use, because
Mainly apply for us is its surface, for material no requirement (NR), therefore more broadens the range of choice.Wherein preferably, plane
The requirement of substrate 2a need to meet following parameter：
Transmitance：T >=75%；
Surface precision PV value：＞ 30um；
Refractive index：Nd=1.4～1.7；
Thickness：T=0.5mm～3mm.
The reflection of polarization film 20 of the present embodiment is that not easily seen face is directed to and itself polarization state identical polarized light or all light lists
Item transmission, the wherein near eye face reflection polarized light vertical with its own.
Embodiment 2：As shown in Fig. 3,5, this different being of embodiment 1：The reflection of polarization piece 2 that the present embodiment is adopted is adopted
Make of different modes, when we do not need the reflection of polarization film 20 changing polarization direction to make using other, due to both
Require light can require to be reflected in nearly eye face in the transmission of not easily seen face again, now require that cooperation cooperation wave plate 21 equiphase is prolonged
Device uses late.Reason is, the common reflection of polarization film only one of which polarization state that the method makes, and commonly polarizes on the market
Reflectance coating only selects through with itself polarization direction identical light, and reflection, with the vertical light in itself polarization direction, does not polarize
Light is from the front or back incidence transmitance feature different with reflectance.During with this kind of common reflection of polarization film, basis is needed to exist
Wave plate or other phase delay devices is added to change the polarization direction of light before concave mirror, otherwise light can be directly through polarization
Reflector plate is mapped on screen, rather than is reflected into human eye 4；And add wave plate equiphase delayer, change the polarization of light
Direction, can be reflected into human eye after this polarized light is got on reflection of polarization piece, as shown in Fig. 2 wherein, wave plate or Phase delay
The selection of device need to meet Phase delay：π/8～3 π/8, optimal choice π/4.
The present embodiment 2 all only selects through with itself polarization direction identical light except have selected common and two sides, instead
Outside penetrating with the common reflection of polarization film of the vertical light in itself polarization direction, one is added to be used for changing also on bi-concave reflecting mirror 3a
Become or postpone outside wave plate 21 or the phase delay device of light π/8～3 π/8 phase place, remaining repeats embodiment 1.
Embodiment 3：
As shown in figure 3, augmented reality near-eye display system, it includes one piece and sends the display screen of polarized light, one piece of polarization
