CAMBRIDGE, Mass., Aug. 6, 2013 — A computational method called light-field moment imaging creates 3-D images using a single, stationary lens, a discovery that could have implications for medical imaging and even future 3-D displays. Principal investigator Kenneth B. Crozier, an associate professor at the Harvard School of Engineering and Applied Sciences (SEAS), and graduate student Antony Orth discovered that by taking two images from the same camera position and focusing them at different depths, a 3-D image can be stitched together. The slight differences between the two images can provide enough information for a...Read full articleRelated content from Photonics MediaARTICLESAR Rapid-Deployment Kits Aid Training, Response to COVID-19To help organizations collaborate and quickly train workers in R&D and manufacturing environments, augmented reality company Apprentice.io is sending dozens of its Tandem Rapid Deployment Kits to...BioPhotonics May/Jun 2020 IssueSmartphone-Measured Photoplethysmography Serves as Digital Biomarker of DiabetesA noninvasive digital biomarker is being developed at the University of California, San Francisco (UCSF) for detecting Type 2 diabetes using a smartphone camera and deep learning algorithm.
