In recent years virtual reality and augmented reality technologies have developed rapidly, yet the visual comfort, experience and practicality of virtual display still need improvement. How to evaluate and measure the key performance, such as optical performance and image quality of virtual display, is an issue of great concern to the industry. An AR/VR virtual image is different from the traditional display, such as LCD, and the measuring method is also quite different. Based on the imaging mode of virtual display, this paper presents the measurement technology to simulate human eye pupil, vision, angle of view and spectral response. The progress of the international standardization of AR/VR virtual display optical measuring methods is introduced as well in combination with the standardization work by the IEC TC110 WG12 "Eyewear display" working group.
