Abstract

The utility model relates to a device for displaying stereo light paths, particularly a device for displaying stereo characters or images. The device is composed of a light source, a beam expanding device, lamp pieces and a light screen which is a nearly transparent stereo object. Through the device, three-dimensional stereo light paths or stereo images can be observed sharply in experiments or presentations without darkrooms. The device can be widely used for shooting teleplays and movies, and for displaying stereos characters or images in advertisement columns.

Description

3 d display device

The utility model relates to the device that is used to show stereo optical path, particularly a kind of device that shows three-dimensional text or image.

The method that is used at present showing stereo optical path in the laboratory is the turbid medium of packing in a transparent container, as emulsion fluid-colloidal solution, smog etc., as screen, allow light beam direct projection screen with this container, according to Tyndall (Tydaee) scattering principle, from the light path side and the screen side observe, study various light paths, it is mainly used in experimental study, is not used for showing stereo-picture or literal as yet.And make people observe the method for stereo-picture on screen or the optical screen or literal at present, and generally adopting polarized light stereo display principle, the observer must wear polaroid glasses.

The purpose of this utility model provides and a kind ofly can show three-dimensional text or image, and particularly before same screen, two different intervals can show the 3 d display device of two width of cloth different images simultaneously.The observer must not wear polariscope just can see stereo-picture, if the observer from an interval when another interval motion, show that image and the color on the optical screen changes thereupon.

The purpose of this utility model adopts following scheme to solve: at least one laser instrument or magic lantern are as light source, light source passes through parallel beam expand device, the lamp sheet, be radiated on the optical screen as image on the lamp sheet or literal, it is characterized in that optical screen is an approaching transparent three-dimensional thing, this solid thing can be the transparent vessel that fills turbid medium, also can be that the transparent thin plate preferably of one or a few blocks (film) is arranged the approaching transparent three-dimensional thing that forms at regular intervals.By three-dimensional optical screen, can make people need not wear polariscope, observe directly the three-dimensional captions or the image that are presented on the optical screen.Adopt this optical screen, the observer can be observed picture clearly in the optical screen front, then image is very faint in the side, for remedying the phenomenon of above deficiency, can adopt two above light sources, throw same optical screen from different perspectives, at this moment, the observer shows two width of cloth different images on different interval visible optical screens.

Adopt the utility model device, can when experiment or demonstration, need not arrive the darkroom and just can clearly observe three-dimensional stereo optical path.The utility model can be used for stereotelevision, film shooting, especially takes three-dimensional text or has certain thickness image, can be used for the exhibition center, the three-dimensional text of advertisement column or the demonstration of image and be easy to conversion; If adopt the number light source beam, can see the different images that shows on the same optical screen in zones of different when the observer is static.When moving, the observer can see that image changes thereupon.This device can also directly be put into the water use or place water surface directive under water, by putting reflective mirror, light is reflected up under water, because general waters all has certain turbidity, so the water surface is especially as a big optical screen.

The utlity model has simple for productionly, service condition is low, advantage such as is widely used.

Fig. 1 represents the work synoptic diagram of 3 d display device;

Fig. 2 represents that the utility model device is another embodiment.

Embodiment 1, the 3 d display device (see figure 1) of being made up of light source 1, parallel beam expand device 2, lamp sheet 3, shell 5, optical screen 4.Optical screen 4 is formed near the turbid medium of containing in rectangular parallelepiped organic glass transparent vessel and the container by one, and container is slightly curved by the one side of observing, and must be with fine sandpaper hacking slightly, and the turbid medium in the container is the water that contains micro-chalk dust.Lamp sheet 3 is scraps of paper that are carved with " H " printed words, and that show on the optical screen 4 is three-dimensional " H ".The color that transmission capacities such as lamp sheet 3 can also be a lantern slide, and lamp sheet 3 is preferably white, orange, red are strong or with the lamp sheet of above-mentioned color as fringing green, blue isochromatic photograph, stereoeffect is better like this.

Embodiment 2, by light source 1, and parallel beam expand device 2, lamp sheet 3, optical screen 4, the 3 d display device that shell 5 is formed, its optical screen 4 is made by multi-layer transparent film or thin plate, and film is put down and is not had Line, thin plate are the thick organic glass of 1～2mm, should arrange at regular intervals between film or the thin plate, and orientation is basic vertical with light path, and for preventing the interference of veiling glare, the arrangement of film or thin plate is not parallel.Optical screen 4 must be with fine sandpaper sand hair slightly by the one side of observing.Its result of use is with embodiment 1.

Embodiment 3, light source 1 is made up of two helium-neon lasers, parallel beam expand device 2, lamp sheet 3, optical screen 4, the 3 d display device that shell 5 is formed, (see figure 2) light source 1 ' be orange figure A, " be red figure B, then observe orange figure A in the I interval, observe red figure B in the II interval; observe the A of partly red partly orange, the image of B half and half between the mesozone; if move to the II interval from the I interval, can see that then figure progressively becomes B by A, while face coloured silk is reddened by orange light source 1.
