scattered light News
New Technique Retrieves Color Images from Scattered Light
DURHAM, N.C., July 30, 2019 — Engineers at Duke University have developed a method for extracting a color image from a single exposure of light scattered through a mostly opaque material. The new approach overcomes the limitations of conventional optical memory effect techniques...
Laser Identifies Size, Shape of Materials for Quicker Optical Design
ST. PETERSBURG, Russia, Sept. 7, 2016 — When optical diffraction was used to analyze the structure of a photonic crystal, researchers found that it created a characteristic light pattern that corresponded exactly to the number of scattering microscopic particles in the sample. The ability...
A Watch on the Watch
Aug 5, 2014 — Whether we use our fingertips to count the pulses thumping in our wrists after a run, or guess our hydration by the amount of water left in our bottles at the end of the day, we’ve all monitored our bodies from time to time – and it can...
Biometric Watches Noninvasively Monitor Vital Signs
WASHINGTON, June 10, 2014 — Monitoring patients’ vital signs is standard medical practice in health care facilities. What happens when people want or need to monitor their vital signs on their own, outside of a hospital or doctor’s office? Researchers from several...
3-D Cell Imaging Through Microfluidic Channels
CAMBRIDGE, Mass., March 26, 2014 — A microscopy technique developed in 2007 by scientists at MIT enabled 3-D imaging of the interior of living cells without using fluorescent or other markers. Recent adaptations have taken this a step further.
NIR Imaging Gets Big Boost
STANFORD, Calif., Dec. 3, 2012 — Studying arterial diseases and therapies just got easier, thanks to a new fluorescence imaging technique that allows researchers to visualize the blood flow of living animals with unprecedented clarity. The Stanford University technique, called...
Unscrambling Scattered Light to Retrieve Sharp Images
ENSCHEDE, Netherlands, and FLORENCE, Italy, Nov. 7, 2012 — A noninvasive method that unscrambles scattered light to retrieve sharp images of objects hidden behind an opaque screen could have important applications in biological tissue imaging.
Listening to Cells with Lasers and Holography
WEST LAFAYETTE, Ind., Feb. 28, 2011 — A Purdue physicist has created technology to detect motion inside three-dimensional tumor spheroids, which may enhance the pharmaceutical industry's early drug discovery capabilities. Physics professor David D. Nolte has developed Holographic...
NSF-Supported Center Moves to Houston
HOUSTON, April 16, 2010 — The National Center for Airborne Laser Mapping (NCALM), supported by the National Science Foundation, has relocated operations to the University of Houston (UH) from the University of Florida. Researchers with the National Center for Airborne Laser...
Light Spots Cellular Suicide
DURHAM, N.C., Feb. 2, 2009 – Bioengineers now are using scattered light to help determine whether cancer cells are responding to chemotherapy. The new technology, developed by bioengineers at Duke University, is helping clinicians more precisely detect within a matter of hours...

OPTICS CATALOG
Nov 1, 2007 — The “Optics and Optical Instruments Catalog, Fall 2007,” from Edmund Optics Inc. highlights the company’s edge-blackened optics, which are designed to eliminate scattered light from optical systems. The color-coded 361-page publication features new...
