Three,For multiple radial reflector elements, the method for handling veiling glare

When using multiple radial reflector elements, the light that light source issues while by corresponding reflective surface, It may also pass through the erroneous reflections of other reflectings surface, if the light of these erroneous reflections finally injects human eye, will form miscellaneous Light.Therefore, it is necessary to take corresponding measure that veiling glare is truncated.There are following three kinds of solutions, such as Figure 13 a~Figure 13 c.

If Figure 13 a is arranged ellipsoidal polarizing plate 1302a1 (special, can to use circular polarizing disk) at light source 1301a, Light is processed into elliptically polarized light (or circularly polarized light), after correct reflecting surface 1303a reflection, using secondary reflection face 1305a (can be plane reflection face or curved-surface reflection side) reflection, since light have passed through two secondary reflections, polarization state The ellipsoidal polarizing plate 1302a2 (special, circular polarizing disk can be used) being arranged in exit direction can just be passed through.And Light is after erroneous reflections face 1304a reflection, and since light only have passed through primary event, polarization state can not pass through ellipse Polarizing film 1302a2, therefore veiling glare will not be generated.

As Figure 13 b is arranged linear polarizer 1302b1, light is processed into linearly polarized light at light source 1301b.Special, Light inherently certain linearly polarized light that light source issues.Throw light under linear polarization state injects correct reflecting surface 1303b generates transmitted light and reflected light.The polarizability of its transmitted light is mutually perpendicular to linear polarizer 1302b2, is blocked, will not Erroneous reflections face 1304b is invested, therefore veiling glare will not be generated；Its reflected light (can be any by polarizability changer 1306b Device that is changeable or destroying the original polarization state of light, such as scattering film, diffraction film, anisotropic membrane, depolarized film, a quarter Wave plate, half-wave plate, full-wave plate etc.), using the reflection of secondary reflection face 1305b, then using polarizability changer 1306b at this point, the polarizability of light has occurred that change, therefore can finally inject people by linear polarizer 1302b2 Eye；

As Figure 13 c is arranged linear polarizer 1302c, light is processed into linearly polarized light at light source 1301c.Special, Light inherently certain linearly polarized light that light source issues.Throw light under linear polarization state injects correct reflecting surface 1303c, correct reflecting surface are a kind of polarization spectro pieces in this scheme.

The characteristic of polarization spectro piece is fully reflective to the light of certain polarization states, and complete to the light of certain polarization states Full impregnated mistake.

Throw light in linear polarization only reflects on the surface correct reflecting surface 1303c, does not transmit, can not Erroneous reflections face 1304c is invested, therefore veiling glare will not be generated；And reflection light passes through the rear polarizer of polarizability changer 1306c Property change, thus can penetrate correct reflecting surface 1303c, inject human eye.

Embodiment 5

In the present embodiment, multiple radial direction reflector elements project each subgraph by side from same direction, regard in human eye Complete image is spliced on nethike embrane.The light between each radial reflector element interferes in order to prevent, may make each Light source issues the light of different polarization states, then by polarization selector, carries out to the light of different radial reflector elements independent Isolation.

Wherein the polarization selector includes various polarizing filters such as linear polarizer or polarization spectro piece.

Multiple radial reflector elements that Figure 14 show the present embodiment project each subgraph by side from same direction. As shown in figure 14, radial reflector element 1401a and radial reflector element 1401b, transmits from top to bottom, projects subgraph by side As 1402a and subgraph 1402b.

Figure 15 a~Figure 15 d, Figure 16 a~Figure 16 d show multiple radial reflector elements of the present embodiment from same direction The specific radial reflector element structural schematic diagram of each subgraph is projected by side.

In shown in Figure 15 a~Figure 15 d, the structure of two radial reflector elements spatially has overlapping, and source ends are provided with Linear polarizer 15021 and linear polarizer 15022, so that the light that light source 15011 and light source 15012 issue has different polarizations State, such as orthogonal linear polarization.

Linear polarizer 15023 and linear polarizer 15024 is arranged in optical line terminal, so that 15021 He of linear polarizer in Figure 15 a The direction of linear polarizer 15023 is consistent, therefore the light that light source 15011 issues finally only is projected by linear polarizer 15023；Together Reason, so that the light that light source 15012 issues finally only is projected by linear polarizer 15024.Since the length of two optical paths is consistent, Therefore the same transmission-type dioptric component 1504 can be shared, human eye is enable to see image clearly.

Figure 15 b, the difference is that, light is first reflected towards outside by reflective structure with attached drawing 15a, then is reflected towards interior. Whole optical path can be made longer using this structure, and make transmission-type dioptric component and linear polarizer 15023 and linear polarization The distance of piece 15024 farther out, to realize more preferably optical effect.Since the length of two optical paths is consistent, can share same One transmission-type dioptric component, enables human eye to see image clearly.

Light is first reflected towards outside by Figure 15 c, reflective structure, invests reflective dioptric component, this is a kind of camber reflection Device, the direction of propagation of meeting deviation light in dioptric, subsequent display effect is affected in order to prevent, needs in reflective dioptric Polarizability changer 1505c is arranged in the surface component 1506c, to change the existing polarization state of all light, so that light is by anti- During penetrating formula dioptric component reflection directive human eye, it will not be blocked again.It, can be with since the length of two optical paths is consistent The same reflective dioptric component is shared, human eye is enable to see image clearly.

Figure 15 d is using a kind of special polarization spectro piece, and as shown in figure optical path, polarised light that light source 15011 issues can be with On its surface, generation is fully reflective without transmiting, and the polarised light that light source 15012 issues only occurs transmission on its surface and do not send out Raw reflection.Polarizability changer 1505d is set on the reflective surface dioptric component 1506d, to change the existing inclined of all light Polarization state, so that will not be blocked again during light is by reflective dioptric component reflection directive human eye.Due to two optical paths Length it is consistent, therefore the same reflective dioptric component can be shared, human eye is enable to see image clearly.

In tetra- kinds of situations of figure 15 above a~Figure 15 d, two different light paths are carried out in two vertical linear polarizations Isolation, similarly, two different optical paths can also be isolated in two opposite circular polarizations, principle is similar, no It repeats.

Figure 16 a~Figure 16 d illustrates other several embodiments that light source, reflecting surface, polarizing film are arranged, wherein light source 16011, light source 16012 is two independent light sources, indicates polarizing film with the rectangle that lines are filled, space rectangles indicate reflecting part Part, i.e. reflecting surface, specific structure is as schemed, it should be noted that:

It all uses linear polarizer as polarization selector in exit, similarly, light can also be carried out using polarization spectro piece Road isolation；

Two different light paths are isolated in two vertical linear polarizations, it similarly, can also be by two differences Optical path be isolated in two opposite circular polarizations.

Since the length of two optical paths is consistent, same nearly eye dioptric component (the transmission-type dioptric component can be shared Or reflective dioptric component), so that human eye is seen image clearly.

It is special such as Figure 16 c, it is possible to use only a light source comes while playing the role of two light sources.For example, in light source 16011 position is put into a light source, this light source can be simultaneously emitted by two kinds of orthogonal polarised lights in polarization direction, and this The different image of two kinds of polarised lights two width of composition (concrete scheme can cover polarizing film by Pixel surface, so that light source surface Two neighboring pixel issues different polarised lights), after this two images is propagated downwards, respectively enters different optical paths, finally exist Complete image is spliced on human eye；Or can to produce two kinds of polarization directions in two different periods mutual for this light source (concrete scheme can place polarizer and corresponding optical channel outside light source, can be in different time by light for vertical polarised light The light that source issues is processed into different polarization states, the method that such as similar Figure 27 a, Figure 27 b are enumerated, or can be using other Different moments generate the optical texture of two kinds of orthogonal polarised lights), and both polarised lights form the different image of two width, Two period switchings rapidly, allow human eye to be detectable the process of switching, just think two images while occurring.

Similarly, such as Figure 16 d, similar method can also be used, plays the work of two light sources simultaneously using a light source With.

Nearly eye display device of the invention, can be realized the through mode display effect of augmented reality, concrete implementation method Include:

1) partial optical structure can permit ambient transmission in nearly eye display device, and keep whole device to the external world The focal length of light is infinity, enables human eye to see external environment clearly, to realize the through mode display effect of augmented reality.

2) transmission-type dioptric component is contained in nearly eye display device, inside, can permit ambient transmission, but can be with certain Focal length to extraneous incident light line carry out dioptric, adding a compensation dioptric component again in the outside of whole device, (such as spherical surface is saturating Mirror, non-spherical lens, Fresnel Lenses etc.), the focal length of focal length and transmission-type dioptric component after cancelling out each other on the contrary, can permit Perhaps human eye sees extraneous light clearly, to realize the through mode display effect of augmented reality.

Nearly eye display device allows ambient light to be directed through without dioptric in one, this programme.

Scheme one

Shown in Figure 32 a~Figure 32 j, using two independent light sources, by respective reflection channel, formation two is independent Radial reflector element produces two subgraphs, and a complete image is spliced on human eye retina, while whole device Ambient light is allowed to be directed through without dioptric.

Shown in Figure 32 a~Figure 32 j, including light source 32011, light source 32012, linear polarizer 3202 is several, and nearly eye is bent Light component 3203, reflection dioptric component 3204, polarizability changer 3205, reflecting surface are several (not marking).Because as shown in the figure Linear polarizer 3202, polarizability changer 3205, several reflectings surface setting so that optical path can only be by unique correctly logical It projects on road.Its principle is identical as aforementioned polarization isolation method, does not repeat.

Scheme two

Figure 33 a~Figure 33 b uses two independent light sources, and image, each direction projection are projected from upper and lower both direction Two subgraphs out.Common property bears four subgraphs, and a complete image is spliced on human eye retina.

Whole device allows ambient light to be directed through without dioptric simultaneously.

In Figure 33 a, including light source 33011, light source 33012, several linear polarizers 3302 reflect dioptric component 3303, Polarizability changer 3304,

Single source issue light be divided to two pieces with different polarization states to center throw, selected by corresponding linear polarizer, It is processed into distance light into correct channel, then by reflection dioptric component, is seen clearly into human eye.

Figure 33 b added plano-concave lens 3305 and plano-convex lens 3306 on the basis of Figure 33 a, keep whole optics On the basis of system external focal length is infinitely great, so that reflection refractive surface and plano-convex lens 3306 on reflection dioptric component 3303 (back and forth twice) realizes shorter dioptric focal length jointly.

In order to realize that better display effect, two Figure 33 a, Figure 33 b schemes all joined polarizability changer 3304.

Light enters the reflection channel of mistake in order to prevent, and more polarizing films or shading can also be added in other positions Piece is to carry out optical path isolation, and details are not described herein again.

Scheme three

Figure 34 a~Figure 34 d is provided to the reflection channel for preventing light from entering mistake and some improvement for carrying out.

Such as Figure 34 a~Figure 34 c, including several polarizing films 3401, dioptric component 3402 is reflected, in certain of Figure 34 a~Figure 34 c Some polarizing films are additionally added in a little positions, and in addition to carrying out optical path isolation to inside display light, additionally aiding prevents ambient By the human eye that is reflected into of multiple reflectings surface, ghost image is formed.

In Figure 34 d, bottom is also added into a piece of horizontal positioned boundary polarizing film 3403 in figure, to prevent light Continue to propagate downwards.Therefore, it can be continued below in boundary polarizing film 3403 and increase other optical textures, without being sent out with top Light out is in contact.

On the basis of the above, more polarizing films or anti-dazzling screen can also be added to carry out optical path isolation in other positions, Details are not described herein again.

Scheme four

Shown in Figure 35, optical path isolation is carried out using polarization spectro piece.

Such as Figure 35, the light that light source 3501 issues becomes by the processing of linear polarizer 35021 and linear polarizer 35022 Two kinds of orthogonal linearly polarized lights in polarization direction.The light projected by linear polarizer 35021 encounters polarization spectro piece When 35051, it can only reflect, will not transmit；The light projected by linear polarizer 35022 encounters polarization spectro piece When 35051, it can only transmit, will not reflect, when then encountering polarization spectro piece 35052, can only reflect, it will not It transmits.

All light invest polarizability changer after the reflection of polarization spectro piece 35051 and polarization spectro piece 35052 3504, after reflecting the reflection of dioptric component 3503, using polarizability changer 3504, hereafter the polarizability of light has been Changed, thus polarization spectro piece 35051 and polarization spectro piece 35052 can be passed through, finally injects human eye.

Meanwhile ambient encounters polarization spectro piece 35051, directly after the reflection of polarization spectro piece 35052 upwards Transmissive will not reflect, therefore will not inject human eye and form ghost image.

Scheme five

Shown in Figure 36, using upper and lower two horizontal positioned light sources, four subgraphs are generated altogether.Including light source 36011, Light source 36012, several polarizing films 3602 reflect dioptric component 3603, polarizability changer 3604, boundary polarizing film 3605.

Such as Figure 36, it joined some polarizing films in apparatus structure, carry out the isolation of four optical paths, while ambient light can be prevented Line reflection repeatedly injects human eye, forms ghost image；It is produced using the light that boundary polarizing film 3605 can prevent upper and lower two light sources from issuing Raw interference.

Preferably, polarizability changer 3604 is added in device outermost, the polarised light in external environment can be made (such as specular light, computer, mobile phone, TV show light etc.) can completely be seen through whole device by human eye.

Scheme six

It is the embodiment of a four subgraph splits shown in Figure 37.

Polarization selectivity, which is used, in end shown in Figure 37 transmits dioptric apparatus 3701.The polarization selectivity transmits dioptric apparatus The characteristics of be that the light passed through can be screened, dioptric only is carried out to inside display light (be in a kind of polarization state), and external Boundary's light (in another polarization state) not dioptric, enables human eye to see internal display light and external environment light clearly simultaneously.

The optical technology for being able to achieve such effect is in the industry cycle existing, and has multiple realization approach, and therefore not to repeat here.

Two, setting compensation dioptric component, realizes the through mode display effect of augmented reality

Transmission-type dioptric component is contained in nearly eye display device, inside, can permit ambient transmission, but can be with certain Focal length to extraneous incident light line carry out dioptric, the outside of whole device add again a compensation dioptric component (such as spherical lens, Non-spherical lens, Fresnel Lenses etc.), the focal length of focal length and transmission-type dioptric component after cancelling out each other on the contrary, allow Human eye sees extraneous light clearly, to realize the through mode display effect of augmented reality.

In Figure 38, in a four subgraph split schemes, internal transmission-type dioptric component 3804 is a positive focal length Lens, and external compensation dioptric component 3803 is a negative focal length lens, so that ambient is after entire optical system, Equivalent focal length is zero, so that human eye can see extraneous light clearly.

Figure 39 a~Figure 39 b show an integrated embodiment of the present embodiment.

Including light source 3901, transmission-type dioptric component 3903 compensates dioptric component 3902, exit window 3904 (several).

It is a kind of 24 subgraphs projection splicing apparatus shown in Figure 39 a~Figure 39 b.Each subgraph is from corresponding exit window Mouth projects, and constitutes a radial reflector element.

In each period, only there are four open in the exit window 3904 of cross-shaped arrangement.Altogether there are six the period, make 24 subgraphs are obtained successively all to project on human eye retina.

Surrounding uses 24 arbitrary sources 3901 or an annular light source.

Wave or turbine type can be used in 24 radial reflector elements.

Each radial direction reflector element optical path length is consistent, and sharing same nearly eye dioptric component 3903 in end, (this example is The nearly eye dioptric component of transmission-type), human eye is seen clearly.

Outside enables human eye to see extraneous light clearly using compensation dioptric component 3902.

Embodiment 10

The different radial reflector element of two optical path lengths the same area on human eye retina projects in the present embodiment Two subgraphs of overlapping, a subgraph is larger, provides wide fringe field of view, and a subgraph is smaller, provides center height Thus the clear visual field provides that edge is broad and the nearly eye display effect of central sharp.

Scheme 1

Figure 45 a~Figure 45 d show the concrete structure schematic diagram of the present embodiment, including light source 45011, light source 45012, son Image 45021, subgraph 45022, polarizing film 4503 (several), reflective dioptric component 45041, reflective dioptric component 45042。

Embodiment proposes a kind of scheme of sized images nesting.

As shown in Figure 45 a, the light that light source 45011 and light source 45012 issue has different polarization states, by different The polarization state of reflection channel selects, and the reflection dioptric component 45041 different from focal length and reflection dioptric component 45042 connect Touching, after reflect dioptric, can simultaneously by human eye it is clear that but due to the focal length of two optical paths difference, cause in human eye view What is be imaged on film is of different sizes.Such as figure, lesser subgraph 45022 and biggish subgraph 45021 are formed respectively.

By the special setting to the image issued on light source 45011 and light source 45012, subgraph 45021 can be made It is just overlapped with subgraph 45022 in linking region, therefore may make user that can not perceive center picture and edge picture Boundary.Since 45022 visual range of subgraph is smaller, clarity is higher, and it is higher that this meets human eye central vision resolving power The characteristics of.

Special, using Figure 45 c scheme, by the setting of different polarizing films, sized images nesting also may be implemented Effect.

Special, using Figure 45 d scheme, reflection dioptric component 45041 is embedded in reflection dioptric component 45042 The heart, and by the setting of corresponding polarizing film, so that the light that light source 45011 issues only can be by reflection dioptric component 45041 Reflection, and the light that light source 45012 issues can only pass through the reflection of reflection dioptric component 45042, so that the isolation of optical path is carried out, It can also realize the effect of sized images nesting.

In addition to using polarizing film, the isolation of optical path can also be realized using the combination of polarizing film and polarization spectro piece.This Place does not repeat.

In Figure 45 a, Figure 45 c, Figure 45 d, if device allows ambient to penetrate, but not ambient is made at dioptric The through mode display effect of augmented reality then can be achieved in reason.In this case, light source 45011 and light source 45012 may be provided at It keeps right in figure side position, light issues to the left, after reflection downwards.

Scheme 2

The present embodiment proposes the scheme of another sized images nesting.

In Figure 46 a, the light that light source 46011 issues, through being reflected towards it is lower after, and be reflected towards by semi-reflecting mirror 4602 Outside, using reflection 4603 dioptric of dioptric component reflection, become the virtual image of luminous position close to light source 46012, therefore can be with The light that light source 46012 issues together, by transmission dioptric component 4604 together dioptric, becomes the light that human eye can be seen clearly.By It has passed through the dioptric twice of negative, positive focal length, therefore the subgraph projected on human eye retina in the light that light source 46011 issues Smaller, clarity is higher.

By the front-rear position of mobile reflection dioptric component 4603, adjustable center subgraph is near human eye retina Focal position, realize the display effect of different focal planes.

Such as Figure 46 b, 4,607 two lens of negative focal length lens 4606 and plano-concave lens are increased in the optical path, can increase light The negative focal length diopter for the light that source 46011 issues.Plano-convex lens 4605 are increased simultaneously, the light of light source 46012 can be made Not by dioptric when line or the light of extraneous transmission pass through plano-convex lens 4605 and plano-concave lens 4607.

It is adjustable by the front-rear position of mobile plano-convex lens 4605, reflection dioptric component 4603, plano-concave lens 4607 Focal position of the center subgraph near human eye retina, realizes the display effect of different focal planes.

Such as Figure 46 c, the light that light source 46011 issues, through being reflected towards it is lower after, semi-reflecting mirror 4602 is passed through, by reflection The reflection of 4603 dioptric of dioptric component, reflects using semi-reflecting mirror 4602, becomes the virtual image of luminous position close to light source 46012, Therefore can be together with the light that light source 46012 issues, by transmission dioptric component 4604 together dioptric, becoming human eye can see clearly Light.

In Figure 46 a~Figure 46 c, if light source 46012 is semi-transparent display, ambient transmission can permit.Then may be used Realize the through mode display effect of augmented reality.Concrete scheme does not repeat.

Scheme 3

The present embodiment proposes the scheme of another sized images nesting.

Figure 47 a~Figure 47 c show the concrete structure schematic diagram of the present embodiment, including light source 47011, light source 47012, partially It shakes piece 4702 (several), transmission-type dioptric component 4703, transmission-type dioptric component 4704, transmission-type dioptric component 4705, reflection Mirror 4706.

Such as Figure 47 a, transmission-type dioptric component 4703 is embedded in the center of transmission-type dioptric component 4704.Light source 47011 is sent out Light out passes through polarization, through being reflected towards it is lower after, and through and being reflected towards outer, due to polarization selectivity, light can only pass through Transmission-type dioptric component 4703 injects human eye, and can not pass through transmission-type dioptric component 4704；The light warp that light source 47012 issues After crossing polarization, human eye can only be injected by transmission-type dioptric component 4704, and transmission-type dioptric component 4703 can not be passed through.By Different in the final optical path length that two light sources emit beam, the focal length of two transmission-type dioptric components is also different, causes two A subgraph it is of different sizes, it is one smaller be located at that center is more visible, and one larger and occupy surrounding it is relatively fuzzy.

In such as scheme of Figure 47 b, joined transmission-type dioptric component 4705 (can be positive focal length, is also possible to negative coke Away from), it can further adjust the projecting light path of center subgraph.Special, pass through the upper of mobile transmission-type dioptric component 4705 Lower position, focal position of the adjustable center subgraph near human eye retina, realizes the display effect of different focal planes.

In such as scheme of Figure 47 c, reflecting mirror 4706 joined, the projecting light path for further increasing center subgraph is long Degree, thus smaller clearer image can be obtained.Special, it is adjustable by the front-rear position of mobile mirror 4706 Focal position of the center subgraph near human eye retina, realizes the display effect of different focal planes.

In conjunction with the explanation and practice of the invention disclosed here, the other embodiment of the present invention is for those skilled in the art It all will be readily apparent and understand.Illustrate and embodiment is regarded only as being exemplary, true scope of the invention and purport are equal It is defined in the claims.
