JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]JAKE SALTZMAN, NEWS EDITOR [email protected]A single-pixel machine vision framework leverages deep-learning designed optical networks to bypass the need for an image sensor-array or digital processor. The system, developed in the lab of UCLA Chancellor’s Professor Aydogan Ozcan, paves the way for tackling certain challenges that are beyond the capabilities of current imaging and machine learning technologies. Most machine vision systems used today use a lens-based camera that sends information to a digital processor that performs machine learning tasks. Even with modern, state-of-the-art technology, these systems suffer...Read full articleRelated content from Photonics MediaArticlesImage-Free Single-Pixel Detection Finds Play in Autonomous MobilityResearchers from the Beijing Institute of Technology have developed a high-speed method to detect the location, size, and category of multiple objects without acquiring images or requiring complex...Photonics.com 5/19/2023Optical Processor Captures Scenes in Spatially Incoherent LightA 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...Photonics.com 8/22/2023Diffractive Optical Network Enables Snapshot Multispectral ImagingUCLA researchers led by Aydogan Ozcan and Mona Jarrahi have developed a multispectral imaging technology capable of turning a monochrome sensor into a multispectral one.
