Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. By packing more details into a 3D image, this type of hologram could enable realistic representations of the world around us for use in virtual reality and other applications.
Technical sessions at this year’s conference centered around four thematic areas: Autonomous Systems, Nanophotonics and Plasmonics, Virtual Reality and Augmented Vision, as well as Quantum Technologies.
Computational Approach Speeds Up Advanced Microscopy Imaging
At upcoming FiO + LS conference, researchers will discuss creative tactics to get rid of loopholes that have long confounded tests of quantum mechanics. With their innovative method, the researchers were able to demonstrate quantum interactions between two particles spaced more than 180 meters (590 feet) apart while eliminating the possibility that shared events during the past 11 years affected their interaction.
Quantum technologies harness the unusual properties of the atomic and subatomic world, where the rules of classical physics do not apply. Properties like entanglement – what Einstein called “spooky action at a distance” – and superposition – where a single particle can exist in multiple states at once – provide remarkable opportunities to push current communications, cryptography, and computing technologies beyond their current limitations. But, what are the latest innovations in quantum research and where are new discoveries taking us?
Scientists at Yokohama National University in Japan have built a highly efficient room-temperature nanometer-scale laser that produces stable, continuous streams of near-infrared laser light. Using only a microwatt of power, this nanolaser design should be useful in future miniaturized circuits containing optical devices.
In efforts that may improve diagnoses of many eye diseases, optics researchers will introduce a new type of laser for providing high-resolution 3-D images of the retina.
In an advance that can potentially assist cancer diagnosis, a new optical technique provides high-resolution, three-dimensional images of blood vessels by taking advantage of the natural multiple-photon-absorbing properties of hemoglobin.
In efforts that can improve studies of biological objects and the construction of nanotech materials, researchers at the University of California-Berkeley have invented "optoelectronic tweezers," a new way of controlling nanometer-scale objects. The research will be presented at the upcoming CLEO/QELS meeting in Baltimore.
At the upcoming CLEO/QELS meeting in Baltimore, an MIT-Sandia team will demonstrate the first real-time terahertz imaging system that obtains images from 25 meters away.
By combining two techniques, magnetic resonance imaging (MRI) and near-infrared optics, researchers at Dartmouth College and Dartmouth Medical School may have devised a new, potentially more accurate method for diagnosing breast cancer.
A new light source based on fiber-optic technology promises to improve the inspection of food, produce, paper, currency, recyclables and other products. New research revealing this technology will be presented at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC), being held March 25-29 in Anaheim, Calif.
South Korean researchers have designed and built an inexpensive optical lens that collects light from a large area and produces a virtually distortion-free wide-angle image. Standing in contrast to commonly known "fisheye" lenses, which produce significant amounts of visual distortion, low-distortion wide-angle lenses can potentially improve image-based applications such as indoor security-camera systems and robot navigation.
Researchers at the University of Missouri-Columbia can now detect the spread of skin cancer cells through the blood by literally listening to their sound. The unprecedented, minimally invasive technique causes melanoma cells to emit noise, and could let oncologists spot early signs of metastases -- as few as ten cancer cells in a blood sample -- before they even settle in other organs.
A new technique sends secret messages under other people's noses so cleverly that it would impress James Bond--yet the procedure is so firmly rooted in the real world that it can be instantly used with existing equipment and infrastructure.
Physicists and medical researchers for the first time have demonstrated a new technique that non-invasively measures in real time the level of damage to the skin from sun exposure and aging, and initial results suggest that women's skin ages faster than men's.
Lee Goldstein of Brigham and Women's Hospital and Harvard Medical School will describe dramatic new developments in the technology during a plenary talk at Frontiers in Optics, the annual meeting of the Optical Society of America (OSA) in Rochester, N.Y., which takes place next week.
