Embodiment Construction
[0033] In order to make it easy to understand the technical means, creative features, goals and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.
[0034] Reference figure 1 , figure 2 , A 3D conversion system using a cylindrical adjuster with lateral light transmission, with a 2D projection lens interface 11 and a projection window 15. From the 2D projection lens interface 11 to the projection window 15, linear polarizers 12 are arranged in order from the optical path. And a quarter wave plate mechanism. The quarter wave plate mechanism includes at least two quarter wave plates, and at least two quarter wave plates with different angles form a closed cylindrical mechanism. The cylindrical mechanism is called polarization modulation The polarization modulator 2 is provided with a rotation axis. It also includes a drive mechanism 14, which is provided with a drive shaft; the drive shaft is lin...

The invention belongs to the optical field and provides a 3D conversion system, particularly, a cylindrical regulator 3D conversion system using side light transmission. A 2D projection lens interface is located at a side surface of a polarized light modulator; a projection window is located at one end of the polarized light modulator; the inner side of the polarized light modulator is provided with a reflector; the 2D projection lens interface is in optical line connection with the projection window through a linear polarizer, a 1 / 4 wave plate mechanism and the reflector; the polarized light modulator is provided with a rotating shaft; the 3D conversion system further comprises a driving mechanism; the driving mechanism is provided with a driving rotation shaft; the driving rotation shaft is in linkage with the rotating shaft; and after passing through the linear polarizer, the 1 / 4 wave plate mechanism and the reflector, light emitted by the 2D projection lens interface is emitted through the projection window and is projected on a polarization-maintaining screen. With the cylindrical regulator 3D conversion system of the invention, a 2D image projected by a 2D projector can be converted into a 3D image.
Description
Technical field [0001] The invention relates to the field of optics, in particular to a 3D conversion system. Background technique [0002] At present, in related technologies, 3D projectors are more expensive than ordinary 2D projectors. At the same time, they also need to be equipped with special shutter glasses. The glasses have built-in batteries, which are inconvenient to wear and complicated in structure, and cost more than polarized glasses. [0003] At the same time, in related technologies, two projectors and two polarizers are used. This method undoubtedly increases the cost of use. In addition, it is necessary to accurately adjust the relative position of the two projectors, which is complicated in operation and poor in consistency. , It is not convenient to use. [0004] There is a more excellent 3D optical conversion system, which realizes 3D conversion by controlling the frequent switching of the left-handed circularly polarized light image and the right-handed circula...
