Abstract

The invention discloses a three-dimensional optical field display system and a display parameter determination method. The system comprises a liquid crystal display panel, a two-dimensional convex lens array, and a holographic function screen. The two-dimensional convex lens array is arranged between the liquid crystal display panel and the holographic function screen. The distance between the two-dimensional convex lens array and the liquid crystal display panel is l; the distance between the two-dimensional convex lens array and the holographic function screen is L; the diameter of each convex lens in the two-dimensional convex lens array; the focal length of each convex lens is f; and the central spacing between the adjacent convex lens is g. The distance 1 between the two-dimensional convex lens array and the liquid crystal display panel, the distance L between the two-dimensional convex lens array and the holographic function screen, and the focal length f of the convex lens meet a Gaussian imaging formula. The divergence angle of the holographic function screen is alpha. On the basis of divergence of the holographic function screen, distortion of the integrated imaging three-dimensional display content can be corrected; and the watcher experience can be improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional light field display, in particular to a three-dimensional light field display system and a method for determining display parameters. Background technique [0002] With the rapid development of today's science and technology, the traditional two-dimensional flat display technology is far from being able to meet the current needs of various industries for depth data and three-dimensional space. More and more application fields, such as medical imaging, scientific research, outer space exploration, important teleconferences and military affairs, etc., require the real reconstruction of 3D scenes, so that the viewer can capture relevant information more accurately and accurately conduct Judgment on the spot. Autostereoscopic display technology can enable viewers to directly experience three-dimensional vision through the naked eye, making three-dimensional images more realistic and display...
