Projection optical device combining augmented reality and glasses

Abstract

The invention provides a projection optical device combining augmented reality and glasses. The device comprises a visual spectacle lens part and an augmented reality optical system part, wherein theeyesight glasses comprise two surfaces, one of which has a fixed curvature shared by the augmented reality optical system, and the other has an adjustable curvature, and by adjusting the curvature, myopia and hyperopia lenses with different degrees can be obtained; and the augmented reality optical system comprises six spherical surfaces, two aspherical surfaces and three free curved surfaces, thefirst spherical surface is shared with the first fixed curvature surface of the spectacle lens. Through the superposition of the glasses and the augmented reality optical system, the functions of glasses and augmented reality display can be realized simultaneously.

Description

technical field [0001] The present invention relates to the field of augmented reality technology, in particular to a projection optical device combining augmented reality with glasses, and in particular to an enhanced, Optical system that combines reality with glasses. Background technique [0002] In recent years, consumer electronics has developed vigorously. After smart phones, virtual reality (VR) and augmented reality (augmented reality, AR) have developed rapidly, and many consumers are chasing related concept products as experience. As a new technology attempt, display devices such as head-mounted displays (HMD) can achieve augmented reality (AR) experience or virtual reality (VR) experience through simple wear, in aviation, engineering, science, medical, games, video , sports, training and simulation and other fields have a wide range of applications. [0003] In the way of realizing AR experience through HMD, the mode of glasses is widely sought after because it ...

Problems solved by technology

[0004] In order to realize the ultra-thin optical transmissive AR display solution, the design of the free-form prism element is introduced, and the optical transmissive AR is realized by using the catadioptric path and the compensating prism. In the case of a good visual experience, the thickness of the optical system of this solution cannot be very thin, which limits the further thinning of glasses-like AR displays; while other designs use planar light waveguide solutions, using light in planar waveguide components The total internal reflection effectively reduces the thickness of the optical element, but the planar waveguide element cannot provide optical power, and it needs to be used with a projection system to obtain a reasonable visual display size. If the matching degree is not good, the wearer's exit pupil position The light distribution is prone to obvious unevenness or even discontinuity, which affects the user's visual experience
