Introduction: Challenge from Bosworth Accepted Several people pointed me to an interesting Instagram video AMA (ask me anything) by Meta CTO Andrew Bosworth on October 21, 2024, that appeared to challenge my October 6th article, Meta Orion AR Glasses (Pt.…

Last week I recorded a roundtable discussion of the new Snap Spectacles and Meta Orion AR glasses. We recorded for 2 hours and I just released the first 30 minutes.

Update: A second reader with expertise in Waveguide believes (but, like my other reader, does not have direct knowledge) that the Snap Spectacles 5 is still using a waveguide with gratings on only one side. This second reader cites the…

Update (Oct. 19th, 2024) While the general premise of this article is that Meta Orion is using similar waveguide technology to Snap (Wave Optics) and that Magic Leap 2 is correct, it turns out that a number of assumptions about…

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…
In my last article, Canon R5 Mk ii Drops Pixel Shift High Res. Is Canon Missing the AI Big Picture? I showed how IBIS High Resolution was useful in improving resolution and reducing moiré/aliasing. Having received my R5 mk. ii (R5m2), I set up a simple resolution and moiré test to compare the R5m2 with its "AI" In-Camera Upscaling to the original R5 with IBIS High Res (IBIS HR).

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.

I saw the Cogni Trax hard edge occlusion demo last week at SID Display Week 2024, and it epitomized the concept of being a "magic show." In this article I explain the concept behind Cogni Trax hard edge occlusion and why I don't think it will ever be practical.
