Researchers Test Imaging Modalities For Accessing Tooth Decay
SAN FRANCISCO, Jan. 19, 2023 — To improve dental health, researchers at the University of California, San Francisco evaluated optical imaging techniques for their efficacy in the identification of secondary tooth decay, which can occur even if a tooth has already been filled. The researchers compared two techniques — shortwave infrared radiation (SWIR) reflectance and thermal imaging — with measurements obtained with optical coherence tomography (OCT) and micro-computed tomography (MicroCT). The results
CMOS-Compatible Photodetector Spurs Possibilities in e-SWIR Band
MONTREAL, May 27, 2022 — High-bandwidth germanium-tin (GeSn) photodetectors, developed by a team at Polytechnique Montréal to support CMOS-compatible technologies in the extended shortwave infrared (e-SWIR) wavelength, could open the way for applications in ultrafast...
