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,...
Hybrid Metalens Supports Miniaturized Optics for Endoscopy
BOSTON, Sept. 20, 2021 — Researchers at Boston University and Harvard University, with colleagues from the Misr University for Science and Technology in Egypt and the University of Waterloo in Canada, developed an achromatic, hybrid metalens that is designed to focus two...
Marine Algae Optical Fiber Boasts Applications in Range of Medical and Scientific Environments
SÃO PAULO, Aug. 7, 2020 — Researchers at the University of Campinas (UNICAMP) in Brazil and Gunma University in Japan have designed an optical fiber from agar, the natural gelatin obtained from marine algae. In addition to being edible, the fiber is biodegradable and...
Researchers Miniaturize Imaging Device Using 3D Microprinted Camera Lens
ADELAIDE, Australia, Aug. 3, 2020 — Researchers from the University of Adelaide and the University of Stuttgart have developed an ultrathin endoscope small enough to scan images from inside the blood vessels of mice. In humans, the scope will help scientists better understand causes...
Lensless Endoscope Produces 3D Images of Ultrasmall Objects
DRESDEN, Germany, Aug. 16, 2019 — Researchers at Dresden University of Technology (TU Dresden) have developed a tiny, self-calibrating endoscope that produces 3D images of objects smaller than a single cell. Without a lens or any optical, electrical, or mechanical components, the...
High-Performance Endoscope Developed for Monitoring Nuclear Waste Reprocessing
CHESHAM, England, Feb. 28, 2019 — Resolve Optics has developed and supplied an infrared endoscope to enable safe monitoring of the glass vitrification process within a radioactive waste processing plant using a thermal camera. The processing plant required a method of monitoring the...
Leibniz Institute Observes Neuronal Structures with Holography
JENA, Germany, Nov. 29, 2018 — Using a multimode optical fiber as thin as a human hair, scientists at the Leibniz-Institute of Photonic Technology have observed at high resolution the neuronal structures inside deep brain areas of living mice. The researchers drew on holographic...
Optics: Form, Function and the Future
Oct 3, 2017 — For all of their diversity of form and function, the vast range of available optical components and optical fibers have much in common — materials, engineering and design, and techniques in fabrication and metrology. And they are among the...
Diffractive Catheter Enhances OCT Imaging
BALTIMORE and SEATTLE, March 12, 2014 — A new imaging catheter that enables real-time, ultrahigh-resolution OCT imaging at 800 nm to form a 3-D volumetric dataset could potentially improve image contrast via increased light scattering and less tissue absorption.
Pushing camera design beyond nature’s limits
URBANA, Ill. – A camera design inspired by the ocular systems found in insects, arachnids and crustaceans is being pushed beyond anything that exists in nature. In the May 2 issue of Nature (doi: 10.1038/nature12083), an interdisciplinary team led by John A....
Fujikura Licenses Patents for CMOS-Based Imaging
TOKYO and DENVER, June 3, 2013 — Fujikura Ltd. and Micro-Imaging Solutions (MIS) will jointly co-market nanosized, disposable CMOS-based endoscopes for minimally invasive medical diagnostics under a licensing agreement the companies announced on Friday. The companies said the...
New Endoscopy System Offers 330-Degree View of Colon
ALPHARETTA, Ga., May 20, 2013 — A new full-spectrum endoscopy system that gives doctors a 330-degree view during colonoscopies may help them miss fewer adenomas during exams, according to a new study presented this week at Digestive Disease Week in Orlando, Fla.
Camera Mimics an Insect’s Compound Eyes
URBANA, Ill., May 1, 2013 — A hemispherical-shaped digital camera that mimics the design of ocular systems found in arthropods offers a wide-angle bug’s-eye view and nearly infinite depth of field for applications ranging from advanced surveillance cameras to miniaturized...
Endoscope Prototype Is Small as a Human Hair
STANFORD, Calif., March 15, 2013 — Some patients dread endoscopy more than the potential diagnosis — but a new prototype is as small as a human hair. And it delivers resolution four times better than previous similar devices of similar design. The device could enable new methods in...
Where the Jobs Are
Aug 1, 2012 — In today’s recovering economic climate, the outlook for jobs in photonics, optics and related disciplines is generally more favorable than it has been and is showing signs of continuing improvement, according to one longtime recruiter for the...
