Description

Unit stereoscopic image display instrument

A kind of stereoscopic image with the stereoscopic image egative film is shown to the unit stereoscopic image display instrument on the screen.

In the past,, two machines were arranged,, in screen, realized the technology of stereo image by different angles in order to satisfy the real day by day requirement of stereo image and science and education aspect in the screen.Though this technology can realize three-dimensional projection, because of two of need or many machines, the stock trick art falls behind, the means complexity, and it is clear to satisfy, simple and practical purpose.

The purpose of this utility model is to realize the purpose that the unit stereoscopic image shows, to satisfy subject and increasingly extensive demands thereof such as biology, anatomy, agronomy, architecture with existing slide projector by objective lens with close the design that resembles the prism group.

The utility model is by slide projector, objective lens, close and resemble prism group composition, slide projector and objective lens are as a whole, closing and resembling the prism group is a separate component, slide projector is traditional slide projector, objective lens is by preceding picture frame, rear mirror frame, every volume, writing that surpasses all the others and 6 lens are formed, wherein lens one are convex lens, come the foremost, and lens two come second for concave mirror behind the lordosis, lens three are biconcave lens, routine every row continuously with biconvex lens 4, between lens two and the lens three the light hurdle is set, lens five are convex lens, convex surface backward, lens six also are convex lens, and convex surface closes forward and resembles the prism group and closed by polaroid and 2 and resemble prism and form, and polaroid 2 block lengths are square, closing and resembling prism side is right angle three pictographs, the front is a rectangle, and the gap is left in the centre, and three parts intermediate space equate.

The course of work of the present utility model is as follows: after Stereogram is by the slide projector projection, the light of right picture passes through after objective lens and the left prism on the Stereogram, obtain polarization axle polarized light at 45, because the polarization axle of the right sheet of the polarized light eyes that the beholder wore also is left-leaning 45 °, both polarization axle unanimities, light can pass through, thus be people's right eye reception, opposite, the light of left side picture, after object lens and right prism, obtain the polarized light of 45 ° of polarization axle Right deviations, just and the polarization axle quadrature of right eye eyeglass, therefore, light is blocked, and can not enter people's right eye

When using the utility model, the polaroid that the utility model uses must cooperate consistent with the polarized light eyes that the beholder is worn, the polarization axle that is left eyeglass lens is parallel with the polarization axle of the left eye picture polarizer, like this, beholder's left eye can only be seen the picture of left eye on the screen, right eye can only be seen the right eye picture, the respective point imaging of each point on the picture on retina, interrelate with optic nerve, give brain with various stimulations, because the difference that each corresponding point are put in retinal epistasy on two pictures just produces the different vision of the degree of depth, these degree of depth differences just make the beholder that the notion of spatial depth has been arranged, thereby obtain real stereoscopic image.

The utility model is a kind of novel solid coil apparatus of finishing by a large amount of research work designs, it is good to have easy to operate, stable performance, precision height, image quality, characteristics such as stereoscopic sensation is strong, can be widely used in fields such as biology, dissection, agricultural, building, higher technology content and potential technology market are arranged.

Fig. 1 totally is provided with figure, and Fig. 2 is the optical texture synoptic diagram, also is that specification digest is with scheming.Fig. 3 is the objective lens structural representation.Each label is respectively among the figure: 1 slide projector, and 2 objective lens, 3 close and resemble the prism group, 4 polaroids, 5 prisms one, 6 prisms, two, 7 lens, one, 8 lens, two, 9 lens, four, 10 smooth hurdles, 11 lens, three, 12 lens, five, 13 lens, six, 14 stereoscopic image sheets, 15,16,17 gaps, 18 lids, 19,20,24,25,26 writings that surpasses all the others, 21 preceding picture frames, 22, connecting thread, border, 23 back frame now in conjunction with the accompanying drawings, provides an example, and the utility model is further described.
