Optical Processor Captures Scenes in Spatially Incoherent Light
LOS ANGELES, Aug. 22, 2023 — A research team led by professor Aydogan Ozcan at the University of California, Los Angeles (UCLA) developed a deep-learning-based approach to designing spatially incoherent, diffractive optical processors. The method provides a way to build all-optical visual processors that work under natural light. Following deep learning, the diffractive optical processors can transform any input light intensity pattern into the correct output pattern. The researchers believe that their design for
