VR systems.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the close-up schematic view of the utility model list eye display system.
Fig. 3 is the structural representation of tradition VR lens combinations.
Reference is：VR equipment frames 10, screen 11, speculum 20, a quarter slide 21, lens 30, analyzing film
31。
Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be further appreciated that, below
The utility model is described in further detail with embodiment with reference to accompanying drawing.
Fig. 1 is referred to Fig. 3：
A kind of VR lens combinations, including VR equipment frames 10, the both sides of VR equipment frames 10 are respectively provided with a screen 11, the length of screen 11
Spend for a, the length of VR equipment frames 10 is b, set two length to outclass traditional VR for a effect of screen 11 and one length is set
For b screen 11 in front, and b<2a, it is clear that the screen 11 that two length are a is more than the screen 11 that single length is b, single
Individual length is b screen 11 due to being limited by human eye interpupillary distance, it is impossible to uses larger screen 11, have impact on viewing effect；
Provided with two lens 30 in VR equipment frames 10, the optical axis of lens 30 intersect with the normal of screen 11 of homonymy, the optical axis of lens 30 with together
The intersection point of the normal of side screen 11 is provided with speculum 20, and one side of the speculum 20 close to front is coated with reflecting material, it is preferred that
Speculum 20, into 45 degree of angles, can effectively reflect the image from screen 11, the energy of speculum 20 with the face immediately ahead of VR equipment frames 10
The influence of screen 11 is all reflexed on lens 30.Screen 11 is arranged at the both sides of VR equipment frames 10 and catadioptric system is used
System, can effectively improve the size of screen 11, the limitation that human eye interpupillary distance is set to the size of screen 11 be eliminated, while screen can also be improved
, there is very big help at 11 resolution ratio and expansion viewing visual angle to the experience effect for improving participant.
The image that screen 11 is sent is projected on speculum 20, and image is reflexed on speculum 20 on lens 30, image
Amplify by lens 30 and incide human eye, set two screens 11 effectively to realize wide-angle effect, and resolution ratio also may be used
Do not limited with significantly improving by human eye interpupillary distance, merge the image of two screens 11, being capable of regarding to one clear solid of participant
Feel effect,.
The light that this VR lens combinations screen 11 is sent is not directly incident on human eye easily by speculum 20, influences viewing
Effect, with reference to Fig. 2, D regions are without reflection also visual region.Further to improve the viewing effect of this VR lens combinations
Really, speculum 20 is provided with a quarter slide 21 close to the one side of screen 11, and the thickness of a quarter slide 21 is typically set to green
The a quarter of optical wavelength, the preceding surface or rear surface of lens 30 are provided with analyzing film 31, by the polarization side of analyzing film 31
To setting with the polarization direction of the emergent light of screen 11 into an angle of 90 degrees.The light of outgoing is linearly polarized light, linearly polarized light on screen 11
Incide on a quarter slide 21, then reflected on speculum 20, and be transmitted through a quarter slide 21 again, it is preferable
Under state, 90 degree of change can occur for the polarization state of the green glow after normal incidence and reflection, can pass through polarization direction and line just
Polarised light incides human eye into 90 degree of analyzing film, and the light of other wavelength can become circularly polarized light or elliptically polarized light, by
In there are different incidence angles, actual (real) thickness and the wavelength of slide are mismatched, and can be approximately considered the light reflected and all be become circle partially
Shake light, exists in circularly polarized light with linearly polarized light into 90 degree of polarised light, this polarised light can be inclined with line by polarization direction
Light shake into 90 degree of analyzing film, and incides human eye；The part linearly polarized light of D regions outgoing is passed directly on lens 30, by
In the polarization direction of analyzing film 31 and the linearly polarized light of the outgoing of screen 11 direction of vibration into an angle of 90 degrees, the portion of D regions outgoing
The linearly polarized light for being passed directly to lens 30 is divided to be intercepted, it is impossible to by lens 30, so can not also reach human eye, not interfere with
The viewing effect of participant.In summary, linearly polarized light is by that can incide human eye after reflecting system, without by anti-
Penetrating the linearly polarized light of system can be intercepted by analyzing film 31, it is impossible to enter human eye, so as to effectively improve VR lens combinations
Viewing effect.
VR equipment is generally head-mounted display apparatus, to improve the comfort level using VR equipment, it should mitigate set as far as possible
Standby weight, VR equipment includes VR lens combinations, and setting lens 30 are Fresnel Lenses, and Fresnel Lenses can not only realize sphere
The effect of lens, and it is lighter, thinner, the weight of VR equipment can be reduced as far as possible.
This VR lens combinations, using system of turning back, eliminate human eye interpupillary distance to screen by setting screen 11 in both sides
The limitation of 11 sizes, significantly improves the size and resolution ratio of screen 11, moreover it is possible to expand the viewing visual angle of participant, set up four/
One slide 21 and analyzing film 31, cause under viewing effect while the image that screen 11 can be overcome to send is directly incident on human eye
The problem of drop so that VR lens combinations can integrally bring superior visual experience to participant.
Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
