The invention provides an optical system for virtual reality display. The optical system for virtual reality display comprises a light source module, a light guiding module, a spatial light modulatorand an optical phase modulation module having a light modulation function of converting planar waves into spherical waves. The light guiding module comprises a horizontal light guider and a vertical light guider. The light source module is located on an incident light path of the vertical light guider, the horizontal light guider is located on an emergent light path of the vertical light guider, the spatial light modulator is located on the emergent light path of the vertical light guider, and the optical phase modulation module is located on the emergent light path of the spatial light modulator. The spatial light modulator of the optical system for virtual reality display does not need to be arranged at a near focal plane of the optical phase modulation module and is compact in structure, small in size and light in weight. Based on a retina image-forming principle, clear imaging can be achieved in a whole display view field range, and a user suffering from shortsightedness or hyperopia can also clearly receive to-be-displayed image information without wearing of 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. 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 myopia or hyperopia correct...
