Abstract

The invention provides a transmissive integral imaging 3D display device based on polarization pinhole array; the device consists of a projector, a polarizing film, and a polarization pinhole array; a normal micro image array forms a polarized micro image array in the space after being projected by the projector and polarized by the polarizing film; the polarized micro image array is combined with the polarization pinhole array to achieve the integral imaging 3D display; lights emitted by a 3D object in the real space is transmitted by the polarization pinhole array to achieve the transmissive display.

Description

technical field [0001] The invention relates to integrated imaging technology, in particular to a penetrating integrated imaging 3D display device based on a polarization pinhole array. Background technique [0002] Penetrating display is a hot research object in the field of display. Viewers can not only watch the content displayed on the display screen, but also watch the scene behind the screen through the display screen, so that the content provided by the display screen and the real scene echo each other. However, currently existing transmissive display screens can only display common 2D image information, and cannot display 3D stereoscopic information. [0003] Integrated imaging 3D display technology uses a microlens array or pinhole array to reproduce a true 3D image. Compared with other 3D display technologies, integrated imaging 3D display has the advantages of no need for visual aids, no coherent light source, full true color, quasi-continuous viewpoint, It has t...
