I think the article merely superimposed manually distorted screenshots from the AVP onto a photo of the sensor, rather than taking a photo of the sensor while turned on, so it's not representative of the distortion, but yes, I agree, you make a good point - the pancake lens optics might be nonlinear, with higher PPD in the center. There's some interesting analysis here: https://kguttag.com/2023/06/26/apple-vision-pro-part-4-hyper... He concludes, by making comparison with the Meta Quest which has similar pancake optics to the AVP, and by scaling up the PPD, that the AVP's PPD could be as high as 39 PPD in the center of the image. I think most of the conclusions derived from the analysis here will still hold true if the central PPD does turn out to be as high as 39, rather than 34. It's still a very long way from 20/20 retina at 60, from foveal cone density at 110, and pales in comparison to the PPD achieved by even entry level 14" laptops or 27" 4K displays. |
