Abstract
The utility model directs to an optical display, composed of a spherical total reflecting mirror, a plane total reflecting, a viewing window, a case and so on, and suitable to exhibit rare objects or objects disallowable to freely touch, such as priceless relics, jewelry or live biological specimens and so on. Because the spherical total reflecting mirror has an enough size, an observer can see a 3-dimension parallactic virtual image respectively through a left eye and a right eye, the exhibited objects can be accessed by just stretching a hand as if floated in the air. The utility model is full of interests and attractiveness and greatly enhances the safety of an exhibition.
Description
One, technical field
The utility model belongs to the optics display instrument design and manufacturing technology in the physics.
Two, background technology
For the article of showing preciousness or not allowing arbitrarily to touch, during as rare cultural relics, bullion or biological living sample etc., common way is these article to be put into the glass showcase of band anti-theft device or a special temperature, humidity requirement, and spectators then can directly see the article of being showed across glass.
In order to increase security and mystique, abroad also have in recent years to be specifically designed to the optics display device product release of showing three-dimensional body.Present being seen three-dimensional optical display device product, what main optics adopted is semi-transparent semi-reflecting lens, optical energy loss is up to 80%.Therefore, only being adapted at the more weak occasion of light uses; And the visual angle of external existing product is also less, and the displaying that is used for public situation still is subjected to certain restriction.
Three, summary of the invention
Purpose of design of the present utility model is, makes a kind of three-dimensional optical display device that can use under intense light irradiation, and increase the visual angle as far as possible, convenient many people appreciate observation simultaneously.
Technical solution of the present utility model is: adopt sphere completely reflecting mirror arranged in pairs (1) and plane completely reflecting mirror (2) optical system.Display material (3) is placed near the focus (centre of sphere) of sphere completely reflecting mirror (1),, can outside three-dimensional optical display device casing, with the naked eye clearly sees the three-dimensional imaging that is demonstrated object by view window (7).
Four, description of drawings
Fig. 1 is the image-forming principle synoptic diagram of three-dimensional optical display device.(1) is the sphere completely reflecting mirror among the figure, and (2) are the plane completely reflecting mirror, and (3) for showing object, (4) are the three-dimensional imaging, and (5) are observer's naked eyes, and (6) are lighting source, and (7) are view window, and (8) are cabinet;
Fig. 2 is a kind of by many three-dimensional optical display device synoptic diagram that sphere completely reflecting mirror (1) and plane completely reflecting mirror (2) are formed.(3) are the displaying object among the figure, and (4) are the three-dimensional imaging, and (7) are view window.
Five, embodiment
Embodiment 1:
The three-dimensional optical display device of forming by a pair of sphere completely reflecting mirror (1) and plane completely reflecting mirror (2), as shown in Figure 1.The spherical radius R=1000mm of sphere completely reflecting mirror (1); Show that object (3) is placed on one and can forward and backwardly moves and on the platform of self axis rotation.Suitably adjust the reflection angle of plane completely reflecting mirror (2) and observer's position, just can outside view window (7), observe the three-dimensional imaging (4) of showing object (3).
Embodiment 2:
By many three-dimensional optical display devices that sphere completely reflecting mirror (1) and plane completely reflecting mirror (2) are formed.Use 5 pairs of sphere completely reflecting mirrors (1) and plane completely reflecting mirror (2) in this example altogether, as shown in Figure 2.The spherical radius R=1000mm of sphere completely reflecting mirror (1).Show that with one object is placed on the centre of sphere place of sphere completely reflecting mirror (1), can allow 5 observers outside view window (7), see the three-dimensional imaging (4) that is demonstrated object (3) simultaneously at least.
The article that the utility model is very suitable for showing preciousness or does not allow arbitrarily to touch are as rare cultural relics, bullion or biological living sample etc.Because sphere completely reflecting mirror (1) has enough sizes, the observer is when observing, and its images of left and right eyes can be seen the three-dimensional imaging (4) with parallax simultaneously respectively, the object that is demonstrated just like be suspended at the moment the air, at arm's length! Be rich in interest and attractive force.But spectators also do not know the true accurate location of object, therefore, have improved the security performance of showing greatly.
Because adopt the sphere completely reflecting mirror (1) and the plane completely reflecting mirror (2) of total reflection, optical energy loss is lower than 20%, so this device still can be known and see the bright three-dimensional picture that is demonstrated object when ambient lighting is strong.
Claims (1)
1. a three-dimensional optical display device of being made up of sphere completely reflecting mirror, plane completely reflecting mirror, view window and cabinet etc. is characterized in that being furnished with in pairs in the cabinet (8) sphere completely reflecting mirror (1) and plane completely reflecting mirror (2).
