  1. OSA Applauds New White House Brain Mapping Initiative 4/3/2013

    The Optical Society (OSA) recently released a statement in support of U.S. President Barack Obama’s proposed Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative.

  2. The Power From The Mirror 7/10/2020

    High-power lasers can only be as strong as their optical components allow. Thus, the further development of laser technology depends crucially on the development of complex coating systems with a high damage threshold.

    Positive Light announces new office on the East Coast
  4. Flying 3D Eye-Bots 5/2/2012

    They can be deployed as additional surveillance resources during major events, or as high-resolution 3D street imaging systems. Intelligent swarms of aerial drones are a universally useful tool for police, crisis managers and urban planners. Special 3D sensors developed by Fraunhofer researchers ensure flawless aerobatics and prevent collisions.

  5. Optical Tractor Beam Traps Bacteria 12/13/2016

    Up to now, if scientists wanted to study blood cells, algae, or bacteria under the microscope, they had to mount these cells on a substrate such as a glass slide.

  6. Colloidal Quantum Dot Light Emitters Go Broadband In The Infrared 9/30/2020

    Broadband light emission in the infrared has proven to be of paramount importance for a large range of applications that include food quality and product/process monitoring, recycling, environmental sensing and monitoring, multispectral imaging in automotive as well as safety and security.

  7. Faster X-Ray Interferometers Emerge Due To Single-Photon Interference 12/28/2007
    By means of X-ray interferometers, lengths down to the mm range can be measured with a resolution of less than one nm. The low translation velocity of the interferometers, which made their use in practice more difficult, could now be increased by a factor of 100 by exploiting the temporal correlation of singly interfering X-ray photons
  8. Mini X-Ray Source With Laser Light 8/14/2015

    Physicists from Ludwig-Maximilians-Universität, the Max Planck Institute of Quantum Optics and the TU München have developed a method using laser-generated X-rays and phase-contrast X-ray tomography to produce three-dimensional images of soft tissue structures in organisms.

  9. Tiny Microlaser Sensors Offer Supercharged Biosensing 5/16/2025

    Researchers have developed a 3D micro-printed sensor for highly sensitive on-chip biosensing.

  10. 'Rectenna' Works At Optical Frequencies 9/28/2015

    Made from a forest of modified carbon nanotubes, a "rectenna" has been used for the first time to convert visible light directly into electricity.
