Abstract

The invention relates to a near-to-eye holographic display system and method. The system comprises a lighting device, a hologram loading device and a near-to-eye projection optical device. The lighting device is used for generating lighting coherent light; the hologram loading device is used for loading a generated hologram, modulating the lighting coherent light by means of the hologram, and conducting diffraction according to modulated light waves so as to generate a three-dimensional diffraction image; the near-to-eye projection optical device is used for projecting the three-dimensional diffraction image as a three-dimensional virtual image. By means of the near-to-eye holographic display system and method, spatial three-dimensional light waves given off by an object are reconstituted by means of the optical theory of interference and diffraction, an actual light field of the light can really reappear, all human eye physiological perception cues are provided, the screen display effect is improved to a great extent, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of optical display, in particular to a near-eye holographic display system and method. Background technique [0002] The world's first head-mounted display device was invented by American scientist Sutherland in the 1960s. For a long time after that, head-mounted displays were mainly used in the military field. With the development of electronic technology, digital image processing technology and precision optical manufacturing technology, head-mounted display technology has gradually entered people's daily life from the military field. [0003] In recent years, the Google Glass product launched by the famous American Internet company Google and Facebook's acquisition of Oculus, which focuses on the field of virtual reality, have attracted people's close attention to the head-mounted display. Compared with smartphones, smart tablets, laptops and desktop computers, head-mounted displays can provide a larger ...
