- gus_massa 5y agoThe problem is the title, but remember that the researchers don't write the title of the press article. It's well known that you can compute any desired linar transformation with light and lens, diffraction gratings and similar stuff. I've see people calculating the wavelets transform with a similar equipment, like 10 years ago. The interesting part of the research article is that they got a better method to design the lens, diffraction gratings and similar stuff to calculate the transformation. This is somewhat explained in the article, but totally lost in the title.
