JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Researchers at the University of Washington have modified the standard process of OCT (optical coherence tomography) to detect minute changes in response to light in individual photoreceptors in the living eye. The technique has potential in the testing of therapies such as stem cells or gene therapy to treat retinal disease. “Typically, retinal OCT systems are implemented by raster scanning a point of light across the retina. This provides excellent contrast, but at the cost of speed due to dual-axis scanning,” corresponding author Ramkumar Sabesan, assistant research...Read full articleRelated content from Photonics MediaArticlesRetinal OCT and Genetics Identify Links Between Ocular and Systemic HealthA study conducted by Mass Eye and Ear, the Broad Institute at MIT, and Harvard Medical School has demonstrated links between the thinning of different retinal layers and an increased risk of disease....Photonics.com 2/1/2024High-speed Raman Method Detects Micro- and NanoplasticsRaman spectroscopy is a useful tool for identifying microplastics — plastic particles smaller than 5 mm — although conventional point confocal Raman methods are limited to single-point...Photonics Spectra November 2023 IssueHyperspectral Machine Vison Finds Its Place in a Growing Number of Sorting and Inspection ApplicationsPICVISA Machine Vision Systems of Spain is striving to make the world cleaner by enabling the automatic sorting of textile waste.
