FIBER OPTICS FEATURES
Optical Fiber Sensors Enable New Biomedical Devices Jun 1, 2022 — The biomedical community recognized the advantages of optical fibers long ago, accepting them even before their adoption for long-haul telecommunications. Early research on the light-guiding properties of fibers in the late 1920s was aimed at applications in medical imaging. The first clad optical fiber was drawn on December 8, 1956, by Larry Curtis, a graduate student under Basil Hirschowitz at the University of Michigan. The technology was used in a multifiber bundle for a fiber endoscope,...
