Referring to fig. 1 to 4, the present utility model provides a 3D macro-screen viewing optical structure, comprising: a reflecting concave mirror 1, a half mirror sheet 2, a half mirror sheet 3, a screen 4 and a screen 5;
the first screen 4 and the second screen 5 are arranged at 90 degrees;
the second half reflecting mirror sheet 3 is obliquely arranged at a 90-degree included angle formed by the first screen 4 and the second screen 5 and forms a certain included angle with the first screen 4 and the second screen 5 respectively;
the half mirror sheet I2 corresponds to the half mirror sheet II 3 and is used for reflecting the light rays of the half mirror sheet II 3; the reflecting concave mirror 1 is arranged at one end of the half mirror plate 1;
light rays emitted by the first screen 4 and the second screen 5 pass through the second half mirror plate 3 and then are reflected to the reflecting concave mirror 1 by the first half mirror plate 2, the reflecting concave mirror 1 reflects the light rays and simultaneously amplifies the picture, and then the light rays pass through the first half mirror plate 2 and enter the 3D glasses 6 of a person to be watched.
The light rays emitted by the first screen 4 and the second screen 5 are polarized light. The angles of polarized light emitted by the first screen 4 and the second screen 5 are different by 90 degrees. One polarized lens of the 3D glasses 6 is consistent with the polarized angle of the polarized light of the first screen 4, and the other polarized lens is consistent with the polarized angle of the polarized light of the second screen 5. The included angle between the half mirror plate II 3 and the screen I4 is 45 degrees, and the included angle between the half mirror plate II 4 and the screen II 5 is 45 degrees. The half mirror plate one 2 is parallel to or intersects with the half mirror plate two 3 (see fig. 4). The first half reflecting mirror sheet 2 is arranged above the second half reflecting mirror sheet 3, and the reflecting concave mirror 1 is arranged at the lower end of the first half reflecting mirror sheet 2.
The working principle of the utility model is as follows:
referring to fig. 2, light emitted from a first screen 4 passes through a second half mirror plate 3 and then is reflected by a first half mirror plate 2, light reflected by the first half mirror plate 2 is further emitted towards a direction of a reflective concave mirror 1, further light is reflected by the reflective concave mirror 1 while a picture is enlarged, and light further reflected by the reflective concave mirror 1 is emitted out of the whole light system through the first half mirror plate 2 for viewing by human eyes. Since the light emitted by the second screen 4 is polarized light, one of the polarized glasses worn by the viewer is polarized light with the polarization angle consistent with that of the polarized light of the first screen 4, the light further passes through the polarized lens with the polarization angle consistent with that of the polarized light of the first screen 4, and is further observed by eyes. The polarized lens worn by the other eye is perpendicular to the polarized light emitted by the first screen 4 (the polarized light is different from the polarized light by 90 degrees), so that the light cannot pass through, and the other eye cannot see the picture light emitted by the first screen 4.
Referring to fig. 3, the light beam emitted from the second screen 5 and reflected by the second half mirror plate 3 is reflected again by the first half mirror plate 2, and the light beam reflected by the first half mirror plate 2 is further emitted toward the direction of the concave mirror 1, and the further light beam is reflected by the concave mirror 1 while the picture is enlarged, and the light beam reflected by the concave mirror 1 is emitted through the first half mirror plate 2 to the whole light system for viewing by human eyes. Because the light emitted by the second screen 5 is polarized light, one piece of polarized light glasses worn by the viewer is polarized light with the polarization angle consistent with that of the second screen 5, the light further passes through the polarized light lens with the polarization angle consistent with that of the second screen 5, and is further observed by eyes. The polarized light lens worn by the other eye is perpendicular to the polarized light emitted by the second screen 5 (the difference is 90 °), so that the light cannot pass through, and the other eye cannot see the picture light emitted by the second screen 5.
Through the demonstration of the two light paths, the effect finally realized is that after a viewer wears polarized glasses, one glasses can only see the enlarged picture of the first screen 4, and the other eye can only see the enlarged picture of the second screen 5, and the complementary interference is realized. The 3D imaging principle can be used for knowing that the first screen 4 and the second screen 5 play 3D content with 3D parallax at the same time, so that a viewer can watch clear 3D content through the optical structure.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
