Abstract

The invention provides a virtual reality display optical system and a pair of virtual reality glasses. The virtual reality display optical system comprises a light source module, a light guiding module, a transparent transmittance type spatial light modulator and a hook face reflection mirror capable of converting plane wave into spherical wave, wherein the light guiding module comprises a horizontal light guider and a perpendicular light guider; the hook face reflection mirror comprises a full reflection membrane; the light source module is arranged on an incident light path of the perpendicular light guider, the horizontal light guider is arranged on an emergent light path of the perpendicular light guider, the spatial light modulator is arranged on an emergent light path of the horizontal light guider, and the hook face reflection mirror is arranged on an emergent light path of the spatial light modulator. The spatial light modulator of the virtual reality display optical system need not be arranged at the position of a near-focal plane of the hook face reflection mirror; the virtual reality display optical system has the advantages of compact structure, small size and light weight; based on a retina imaging principle, the virtual reality display optical system can form images clearly in the whole display view field range, and myopia or hypemetropia users can clearly receiveimage information to be displayed without wearing correction glasses.

Description

technical field

[0001] The invention relates to the technical field of optical display, in particular to a virtual reality display optical system and virtual reality glasses. Background technique

[0002] At present, the principle of the general visual optical system of the virtual reality display optical system is to place the display screen at the focal plane position of the focusing lens (such as a spherical lens or an aspheric lens or a Fresnel lens), and use the basic geometrical optics principle, that is, in-focus After the point object passes through the lens, it becomes a magnified and upright virtual image, and the magnified and upright virtual image of the display screen is projected in front of the user's eyes. The virtual reality display device adopting this method needs to place the display screen at the near focal plane of the focusing lens, which has a large volume and heavy weight and poor wearing comfort. Moreover, for myopia or hyperopia users need to wear...
