Varjo XR-4 promises mixed reality that's "nearly indistinguishable from natural vision"

Varjo刚刚宣布了XR-4系列，这是他们针对企业和政府推出的最新一款超高端PC头戴式显示器。Varjo的XR-3现在已接近三年，而新的XR-4系列在显示屏、光学器件、透视等方面带来了显著改进，同时将基础价格降低了数千美元。像以往Varjo的所有头戴式显示器一样，它需要一台配备高端显卡的强大PC，并且必须连接。

Since 2019VR-1 Since their launch, the unique selling point of Varjo headsets has been that they have retinal resolution, meaning that a small area in the center of the field of view beyond what the human eye can resolve is achieved by slicing the image from each lens to Implemented on the secondary "focus" microdisplay.

The Varjo XR-4 ditches these secondary microdisplays, instead using a separate 4K LCD panel for each eye. Because Varjo's aspherical lens has a highly variable magnification that is much larger at the periphery than in the center, it achieves a resolution of 51 pixels per degree in the center, which is close to the commonly accepted standard of 60 PPD for retinal resolution.
