Abstract
The utility model discloses an internal memory visual target displaying device, which comprises a casing and an electronic displaying system. The displaying device also comprises a plurality of optical systems, and a plurality of optical displaying windows are correspondingly arranged on the casing. The utility model combines the electronic displaying and the optical displaying through adding the optical systems based on the original visual target displaying device, can fully reflect the detecting figures of the eyesight visual target, and the optical systems adopts the direct irradlation method, the luminous energy losing is small, and only the small light source can reach the requirements of the displaying polarization, a complicated optical system is not required, the structure is simple, the realization cost is low, and can display multiple figures of polarization, etc.
Description
Technical field
The utility model relates to a kind of sighting target set display, specifically is meant a kind of optics the demonstration and internal memory formula Optotype presenting apparatus that the electronics demonstration combines.
Background technology
Nowadays show that with electronic consoles such as liquid crystal displays the product of various figures is more, technology is improved ripe, as computer visual chart, digital visual function detecting instrument etc.And a figure that detects polarization is arranged in sighting target detects, just can't realize by existing Optotype presenting apparatus.
Summary of the invention
It is a kind of simple in structure that the utility model provides, and realizes that cost is low, but the internal memory formula Optotype presenting apparatus of display digit sighting target, E word sighting target, C word sighting target, animal pattern, red green pattern, pattern of polarization, colour blindness pattern etc.
A kind of internal memory formula Optotype presenting apparatus comprises housing and electronic display system, and described display device also includes several optical presentation systems, and housing is provided with several optics display windows.
Described optical presentation system comprises cone, and cone inwall center is provided with light source, is pasted with picture on the cone front port, posts polaroid on the picture, and the polaroid outside is provided with glass.
Described optical presentation system comprises cone, and cone inwall center is provided with light source, and cone front port the place ahead is provided with polaroid, and polaroid the place ahead is provided with the glass of built-in check pattern.
Described cone front port can be arranged with locating rack, and picture is pasted on the locating rack, and locating rack is provided with fixed screw.
Described electronic display system is made up of electronic console and electronic control system.
Described electronic display system is made up of the external image read-out of electronic console.
Image read-out can be DVD figure camera or digital type image systems such as USB flash disk, MD card.
The utility model is by increasing optical system on the basis of original Optotype presenting apparatus, the electronics demonstration is combined with the optics demonstration, can demonstrate fully the test pattern of eyesight sighting target, and optical system of the present utility model adopts the direct irradiation method, and optical energy loss is less, only needs faint light source just can reach the requirement that shows polarization, do not require complicated optical system, simple in structure, realize that cost is low, can show multiple patterns such as polarization.And on electronic image shows, also can adopt DVD optic disk formula mechanical arrangements to show or the dynamic and static demonstration of electron scanning formula memory image.

Embodiment
As shown in Figure 1, 2, a kind of internal memory formula Optotype presenting apparatus, comprise housing 1, by the electronic display system that electronic console 2 and electronic control system 4 are formed, also be provided with several optical presentation systems 5 in the display device, correspondence is provided with several optics display windows 3 on the housing 1.
As shown in Figure 3, optical presentation system 5 comprises cone 6, and cone 6 inwall centers are provided with light source 7, will detect the front end face that picture 9 is pasted on cone 6, and polaroid 10 is affixed on and detects on the picture 9, and polaroid 10 outsides are provided with glass 12.
Also can be on cone 6 front ports a sheathed locating rack 8, will detect picture 9 and be pasted on the locating rack 8, locating rack 8 is provided with fixed screw 11.
Polaroid 10 can require to be adhered on the detection picture 9 as 45 ° or 135 ° according to polarization, positioning of rotating frame 8, and when forwarding the desired position to, rotation fixed screw 11 is with locating rack 8 location.After light source 7 energising, irradiate light is to detecting on the picture 9, because the effect of polaroid 10, only shows the pattern behind the polarization on the glass 12, at this moment just sees pattern of polarization by optics display window 3.
This optical presentation system adopts the direct irradiation method, and optical energy loss is less, only needs faint light source just can reach the requirement that shows polarization, does not require complicated optical system, and is simple in structure.
Aspect electronic display system, also can adopt electronic console 2 external image read-outs to realize, image read-out can be DVD figure camera or digital type image systems such as USB flash disk, MD card, promptly adopts DVD optic disk formula mechanical arrangements to show or the dynamic and static Display Realization of electron scanning formula memory image.
