1results about How to "Expand monocular field of view" patented technology

The invention provides an optical system and a VR device. In the optical system, each optical path corresponding to two eyes respectively comprises two prisms, moreover, effective optical surfaces ofthe two prisms at least contains one free-form surface, consequently, a monocular field angle is expanded effectively, and a user can observe a relatively big field range through a optical structure corresponding to the left eye or the right eye, and when a target imaging object is a display screen, improvement of screen utilization rate and resolution of the display screen is facilitated.
