Abstract
The invention discloses a high-resolution 3D display device based on a dual-polarization composite pinhole array. The high-resolution 3D display device comprises a display screen, a polarization composite pinhole array I and a polarization composite pinhole array II. The one-dimensional light-transmitting pinhole I and the one-dimensional light-transmitting pinhole II correspond to one-dimensional image elements; the two-dimensional light-transmitting pinhole I and the two-dimensional light-transmitting pinhole II correspond to two-dimensional image elements; a part of light emitted by each one-dimensional image element passes through the polarization composite pinhole array I to reconstruct a one-dimensional 3D image; a part of light emitted by each one-dimensional image element passes through the one-dimensional light-transmitting pinhole I corresponding to the image element, and a one-dimensional 3D image is reconstructed; a part of light emitted by each two-dimensional image element passes through the polarization composite pinhole array I, and a two-dimensional 3D image is reconstructed; a part of light emitted by each two-dimensional image element passes through the two-dimensional light-transmitting pinhole I corresponding to the image element, and a two-dimensional 3D image is reconstructed; and the reconstructed one-dimensional 3D image and the reconstructed two-dimensional 3D image are combined into a high-resolution 3D image in a viewing area.
Description
technical field [0001] The present invention relates to 3D display, and more specifically, the present invention relates to a high-resolution 3D display device based on a dual-polarization composite pinhole array. Background technique [0002] Integrated imaging records the information of the 3D scene to the photosensitive film, and uses the principle of reversible optical path to project the information on the photosensitive film into the imaging space to reconstruct the 3D scene. Compared with other 3D displays, integrated imaging 3D displays have the advantages of continuous viewing viewpoints, no need for visual aids, and coherent light. The prior art scheme uses a composite rectangular multi-pinhole array to increase resolution: the composite rectangular image element array includes a one-dimensional rectangular image element and a two-dimensional rectangular image element, and the one-dimensional rectangular image element and the two-dimensional rectangular image eleme...
