    "body_text": "Researchers reported a random-projection optical neural network whose diffractive encoder can be printed in about 15 minutes and supplies roughly four million optical neurons at 500-nanometer spacing. A fixed physical layer scatters light into a high-dimensional representation; a digital readout with about one thousand trainable weights performs classification. Reported benchmark accuracy reached 97% to 99%. This is a laboratory demonstration, not a general-purpose optical computer, but it shows that one quickly manufactured optical front end can be reused across tasks.",
