Abstract

The invention aims at providing an optical system which comprises a first lens and a second lens. The system is characterized in that the first lens includes a positive focal power, the second lens includes a negative focal power, the first lens comprises first and second convex surfaces, the radian of the first convex surface is lower than that of the second convex surface, the first convex surface is adjacent to an entrance pupil surface, the second lens comprises first and second concave surfaces, the radian of the first concave surface is lower than that of the second concave surface, the second convex surface is adjacent to the first concave surface, and the second concave surface is adjacent to an imaging surface. Thus, optical aberration is corrected more effectively, the light angle of the optical system is improved, the optical system can improve the immersion of a virtual reality device when being used in the virtual reality device, and the amount of used lenses is small and the image interpreting power of the lenses is improved under the condition that requirements for processing technologies are met.

Description

technical field [0001] The present application relates to the field of optics, and in particular to an optical system technology. Background technique [0002] Virtual Reality (VR) is an advanced human-computer interaction technology that most effectively simulates people's behaviors of seeing, hearing, and moving in a natural environment, enabling participants to directly explore the role and changes of virtual objects in their environment , as if in a virtual reality world, generating immersion, imagination and interactivity. With the wide application of virtual reality technology in various fields such as military simulation, industrial simulation, digital city, digital entertainment and e-commerce, various virtual reality products are emerging in the market. At present, optical lenses used in the optical part of VR equipment , most of them adopt single-chip Fresnel single-chip optical design, and the lens layout is as follows figure 1 As shown, including entrance pupil...
