JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Researchers at the University of Tokyo have developed a technique to drastically increase the speed of infrared spectroscopy. The technique, called time-stretch infrared spectroscopy, surpasses dual-comb spectroscopy nearly 10× over. The research could enable observation of very quick chemical reactions, as well as new applications in high-speed imaging or label-free flow cytometry. “I have worked on developing dual-comb spectroscopy for a while and noticed its advantages and disadvantages, and realized that we need another technique to improve its measurement speed with...Read full articleRelated content from Photonics MediaArticlesFree-Form Dual Comb Technology Improves Gas Leak DetectionA smart dual-comb spectroscopy (DCS) technique, from the scientists at the National Institute of Standards and Technology (NIST), detects gases and other substances with more speed and sensitivity...Photonics.com 10/22/2024Raman Spectroscopy Gets Major Speed UpgradeResearchers at the University of Tokyo have increased the measurement rate of Raman spectroscopy by 100-fold.
