Since starting this blog, I have been interested in AR optical designs that are different from others I have seen. When Xreal showed their Xreal One Pro at CES 2025, I was curious to know how it worked. As it turned out, the design was not as different as I had first thought. But the journey lead me to find some connections between Xreal's optical design and that of, Ant-Reality which was reportedly acquired by Google.

It seems like all of a sudden, several companies including Meta are talking about the issue of disparity. Of particular issue with Meta, Magic Leap, and Avegant is the issue of visual distortion due to the frame twist of AR glasses frames.

Introduction January has always been a crazy month for me. I met with and/or saw presentations from over 29 companies at CES and 59 companies at AR/VR/MR and took about 2,000 between the two conferences. As discussed in SPIE AR/VR/MR…

Introduction While Meta’s announced Orion prototype AR Glasses at Meta Connect made big news, there were few technical details beyond it having a 70-degree field of view (FOV) and using Silicon Carbide waveguides. While they demoed to the more general…

Introduction Based on information gathered at SID Display Week and AWE, I have many articles to write based on the thousands of pictures I took and things I learned. I have been organizing and editing the pictures. As its name…

The optics R&D company Hypervision provided a detailed design analysis of the Apple Vision Pro's optical design in June 2023 (see Apple Vision Pro (Part 4) - Hypervision Pancake Optics Analysis). Hypervision just released an interesting analysis exploring whether Micro-OLEDs, as used by the Apple Vision Pro, or LCDs used by Meta and most others, can support high 60 pixels per degree, angular resolution, and a wide FOV. Hypervision's report is titled 60PPD: by fast LCD but not by micro OLED.

Many media outlets, large and small, both text and video, use this blog as a resource for technical information on mixed reality headsets. I follow up with a discussion the "Information Density issue" of virtual versus physical monitors touched on in the LTT video.

My last article Apple Vision Pro’s Optics Blurrier & Lower Contrast than Meta Quest 3, as should be expected, drew many comments (on my blog and elsewhere) saying that the Apple Vision Pro (AVP) was sharper than the Meta Quest 3 (MQ3). While I had checked it many times before releasing the previous article, I decided to go back and check again. This time, I used various applications on the AVP to show the same image with a side-by-side comparison. Surprisingly, displaying an image stored on the AVP from a folder gave me different results than other methods/apps.

I have taken many thousands of pictures through dozens of different headsets, and I'm noticing when looking closely at the pictures that the Apple Vision Pro (AVP) image is a little blurry. So I decided to compare the AVP to the Meta Quest 3 by taking the same image at the same size in both headsets.

I often say and write, "The simple test patterns are often the toughest for display systems to get right because the eye will know when something is wrong. If a flat white image is displayed and you see color(s), you know something is wrong.
