Abstract
The utility model relates to an optical imaging device, in particular to an optical lens combine with a display, the utility model realizes an image-forming system nearly sound-surround ambiance, an optical lens is relatively parallel to a video display. The optical lens is a convex lens. The outside size of the video display is greater than the outside size of the optical lens. The outside size of the video display is equal to the outside size of the optical lens. The video display is connected with the optical lens through a connecting link. The field coverage of human eyes can be placed at the full view of the video image by the optical imaging device, generating the virtual effect of watching full view video image. And the focus can be adjusted by the optical imaging device, satisfying the request of clearly watching video full view virtual image by different sight human.
Description
Affiliated technical field: the utility model relates to a kind of optical imaging device, particularly combines with display about optical mirror slip, realizes being close to the imaging system of telepresenc.
Background technology: known virtual optics imaging system has three kinds of light path systems, that is: coaxial eyepiece multi-disc lens amplify light path system, amplify light path system from shaft type free form surface internal reflector light path system and from the reflection of shaft type concave mirror.The weak point of said system is: one, the non-adjustable or difficult accent of focal length.Reason be above-mentioned optical system or because of design, processing is fixing is shaped, or because of the more and difficult adjustment of eyeglass.Two, the imaging picture is less, and the window frame sense is heavier.Reason is that the display plane of above-mentioned optical system all must make and more can not realize panoramic virtual in the frame imaging simultaneously at display surface and display surface edge, the visual field of having limited eye less than camera lens reflection and amplification face.Enlarging picture is difficult to overcome with the contradiction that reduces camera lens.Three, above-mentioned optical system or because of the many weight of camera lens heavier, or because of design, processed complex cost higher.
Summary of the invention: the purpose of this utility model is: a kind of optical imaging device is provided, and it can place the human eye visual field panoramic video image, produces the virtual effect of watching the panoramic video image.And adjustable focal length, satisfy the requirement that different eyesight persons clearly watch the video panorama virtual image.
The technical solution of the utility model is: design a kind of optical imaging device, it is characterized in that: the optical lens opposing parallel is in video display.
The optical lens of described optical system is convex lens.
The video display Outside Dimensions of described optical system is greater than the optical lens Outside Dimensions.
The video display Outside Dimensions of described optical system equals the optical lens Outside Dimensions.
The video display of described optical system is connected by connecting link with optical lens.
The video display of described optical system and the distance between the optical lens are regulated by variable valve.
The display surface of the video display of described optical system is the plane.
The display surface of the video display of described optical system is a curved surface.
The optical lens of described optical system is the monolithic convex lens.
Compared with the prior art the utility model has following advantage:
1, owing to adopt the monolithic convex lens, thus design, make, processing is very simple, material source is extensive, price is low.And than multi-disc and light from shaft type camera lens weight.
2, since the video display Outside Dimensions of optical system greater than the optical lens Outside Dimensions, so for realizing that the panoramic virtual image provides possible.
3, because the joint of the adjustable focal length in the optical system is applicable to that the wearer of various eyesights watches.
The invention will be further described below in conjunction with the embodiment accompanying drawing.
Description of drawings:
Fig. 1 is embodiment 1 a midplane display optics imaging system structure side view.
Fig. 2 is embodiment 1 a midplane display optics imaging system structure vertical view.
Fig. 3 is embodiment 2 mean camber display optics imaging system structure side views.
Fig. 4 is embodiment 2 mean camber display optics imaging system structure vertical views.
Fig. 5 is panoramic virtual principle and a visual field synoptic diagram among the embodiment.
Among the figure: 1, eyes; 2, convex lens; 3, flat-panel screens; 4, connecting link; 5, variable valve; 6, Yan photocentre; 7, field angle; 8, virtual image; 9, curved surface display.
Embodiment 1 is as shown in Figure 1: convex lens 2 are connected with flat-panel screens 3 opposing parallel by connecting link 4.
During use as shown in Figure 2: convex lens 2 are connected with flat-panel screens 3 opposing parallel by connecting link 4.
As shown in Figure 5, Alpha is the field angle of eyes 1, and beta is the extended line of line of display screen 3 points outside A and convex lens 2 points outside C and the angle of optical axis OO '.Because beta=arctgAB/2 (u+x), Alpha=2arctgCD/2x, so when satisfying beta＞Alpha/2=arctgCD/2x, the field angle 7 of eye 1 will be within the scope of virtual image 8, video image frame phenomenon disappears.
Fig. 4 is embodiment 2 user mode synoptic diagram.
The variable valve 5 of Fig. 1 and Fig. 3 is used to regulate the distance of flat-panel screens 3, curved surface display 9 and convex lens 2, with the needs of the onlooker that adapts to different eyesights " distance of distinct vision ".
