- DarkSucker 9mo agoThe paper describes a split Alvarez (Lohmann) lens [1,2] with a phase modulator between them. I didn't do the math, but it looks like the phase modulator is optically equivalent to a mechanical shift of the Alvarez lenses over regions of the field of view. Alvarez lenses have higher aberrations, and are relatively bulky, compared to normal lenses. AR was referenced in the paper, but this lens will be hard to make compact, and have great image quality, over large fields of view. 1. https://www.laserfocusworld.com/optics/article/16555776/alvarez-lens-enters-the-real-world https://www.laserfocusworld.com/optics/article/16555776/alva... 2. https://pdfs.semanticscholar.org/55af/9b325ba16fa471e55b2e499c9704120b5040.pdf https://pdfs.semanticscholar.org/55af/9b325ba16fa471e55b2e49...
