Abstract

The invention discloses a zoom three-dimensional display optical system based on a deformable mirror and a helmet display. The zoom three-dimensional display optical system based on the deformable mirror comprises a display and the deformable mirror, the zoom three-dimensional display optical system based on the deformable mirror is provided with a viewing position for being viewed by human eyes,a display light path is formed between the display and the viewing position, and the deformable mirror is arranged on the display light path. According to the technical schemes, an active optical element, the deformable mirror, is used in an optical system of the helmet display to adjust the focal length, and thus the problem of the difference of the regulation effect and the convergence effect inexisting helmet display is solved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display devices, in particular to a zoom three-dimensional display optical system based on a deformable mirror and a helmet display. Background technique [0002] Three-dimensional display technology has become a hot field of research and invention in recent years. There are many three-dimensional display technologies that have been proposed, such as helmet-mounted display (HMD) technology, immersive projection display technology, volume display technology and holographic display technology. Among various three-dimensional display technologies, helmet-mounted display technology is currently the most widely used three-dimensional display technology. The helmet-mounted display uses glasses to separate two images with a certain parallax at the same time, and each glasses receives an image, so that the observer can receive a stereo image pair with parallax to generate depth perceptio...
