Problems solved by technology

[0003] The half eye viewing angle of the existing eyepiece optical system is small, which makes the observer feel that the vision is narrow, the resolution is low, and the aberration is so serious that the display screen needs to be compensated first. Therefore, how to increase the half eye viewing angle and enhance the image quality The system is a problem that needs improvement

Abstract

The invention discloses an eyepiece optical system, which is used for imaging light entering the observer's eyes from a display screen through the eyepiece optical system for imaging. The direction facing the eyes is the eye side, and the direction facing the display screen is the display side. The eyepiece optical system sequentially includes a first lens, a second lens and a third lens along an optical axis from the eye side to the display side, and each of the first lens, the second lens and the third lens includes an eye side and a display side. The second lens has positive refractive power, and the display side of the second lens has a concave portion located in the vicinity of the optical axis.

Description

technical field [0001] The invention relates to the field of optical systems, in particular to an eyepiece optical system. Background technique [0002] Virtual reality (Virtual Reality, VR) is to use computer technology to simulate a three-dimensional virtual world, providing users with visual, auditory and other sensory simulations, allowing users to feel personally on the scene. At present, existing VR devices are mainly based on visual experience. The parallax of human eyes is simulated by splitting images with slightly different viewing angles corresponding to the left and right eyes to achieve stereoscopic vision. In order to reduce the size of the virtual reality device and allow users to obtain a magnified visual experience through a smaller display screen, the eyepiece optical system with magnification function has become one of the subjects of VR research and development. [0003] The half eye viewing angle of the existing eyepiece optical system is small, which ...
