Thanks, I added a section called "Principle of operation" to explain how it works.

What's your FPS/LPS in this setup? I've experimented with similar imaging with an ordinary camera, but LPS was limiting, and I know line-scan machine vision cameras can output some amazing numbers, like 50k+ LPS.

Absolutely fascinating stuff! Thank you so much for adding detailed explanations of the math involved and your process. Always wondered how it worked but never bothered to look it up until today. Reading your page pushed it beyond idle curiosity for me. Thanks for that. And thanks also to HN for always surfacing truly interesting reading material on a daily basis!
