Optical transmission projection type three-dimensional helmet display

Abstract

The invention discloses an optical transmission projection type three-dimensional helmet display, which consists of a short-distance microprojection system, a spectroscope and a user screen. The short-distance microprojection system has a special structure consisting of an eye lens and a projection objective. A lens 2 serves as the eye lens and also is part of the short-distance microprojection system, so that the image projected on a screen by the projection system is a clear rear image, and the image on the scattering screen is amplified by the eye lens and reflected into human eyes by a half-reflecting half-transmission lens, and formed at a relatively far place.

Description

An optical transmission projection stereoscopic helmet-mounted display technical field The invention relates to an optical transmission projection stereoscopic helmet display optical system, which is especially suitable for virtual reality or augmented reality systems. Background technique Sir Charles Wheatstone, a British inventor, invented the first 3D stereoscopic screen viewer based on the principle of parallax in 1838, but at that time photos had not yet been invented, and pictures drawn by hand were used. In 1859, Oliver Wendel Holmes improved the patent of Joseph Bates and invented the hand-held pocket screen viewer, whose principle has been popular until today. Since the observed image of the stereoscopic screen viewer is a picture for a long time, the stereoscopic image cannot be played continuously, and its use has been limited to a certain extent. The stereo vision of the helmet display technology is also based on this principle. The advantage of picture disp...
