IEC 62629-62-11:20 22规定了用于确定由3D显示设备和虚像光学器件（例如平视显示器）创建的图像的光学特性的标准测量条件和测量方法。虚像是指3D视觉信息与外部世界重叠的图像。然而，眼睛佩戴型显示器超出了本文档的范围。 笔记？虚像在光学中的含义一般是当从物体上的一点发出的光线总是发散时形成的图像。关于显示应用，可以根据实际观看情况来解释虚像。当一个图像被观看时，即使没有物理显示器（监视器、电视、屏幕），在人的眼前，它也被称为虚像。

IEC 62629-62-11:2022 specifies the standard measuring conditions and measurement methods for determining the optical properties of the image created by 3D display devices and virtual-image optics such as head-up displays. The virtual image refers to an image in which the 3D visual information is superimposed with the outside world. Eye-wear type displays are however beyond the scope of this document.
NOTE？The meaning of a virtual image in optics is in general an image formed when the outgoing rays from a point on an object always diverge. With regard to display application, a virtual image can be interpreted according to a real viewing case. When an image is viewed, even though there is no physical display (monitor, TV, screen), in front of a person's eyes, it is called virtual image.
