  1. Researchers Use Quantum Entanglement To Detect Radio Waves

    Scientists have devised a new technique that uses quantum entanglement of a million rubidium atoms to detect weak radio waves as accurately as the most sensitive radio frequency magnetometers available.

  2. Light-Trapping Sensor Improves Spectroscopy By Leaps And Bounds

    A new light-trapping sensor fabricated by engineers at the University at Buffalo has been demonstrated to be capable of up to 1,000 times greater resolution than existing spectroscopy devices that detect minute amounts of substances.

  3. Researchers Create Beamsplitter For Polarizing Light At Terahertz Frequencies

    Researchers at Brown University and Osaka University have developed a technique to polarize light for terahertz waves using a new type of beamsplitter made from stacks of spaced metal plates. 

  4. Stackable Metamaterials Using Computer Chip Technology Make For Novel Retroreflector

    Engineers at the California Institute of Technology (Caltech) have designed and fabricated a unique type of retroreflector built from stackable metamaterials using computer-chip manufacturing technologies, allowing them to be integrated into optoelectronic devices.

  5. Photodetector With Nanocavities Key To Smaller Optoelectronics

    Researchers at the University of Wisconsin–Madison (UW-Madison) and the University at Buffalo (UB) have developed a very thin yet high-performance photodetector consisting of nanocavities sandwiched between a single-crystalline germanium and a reflective layer of silver.

  6. Scanning Microwave Microscopy For Non-Destructive Imaging Of Silicon Nanostructures

    Academe and industry collaborators in Europe have developed a scanning microwave microscope capable of imaging three-dimensional, atom-sized components buried within silicon chips, making it one of the first devices to image and characterize, in a non-destructive way, those structures that are considered building blocks of quantum devices.

  7. ViDAR Optical Radar Installed In SKELDAR V-200 Unmanned Aerial Vehicle

    ViDAR (visual detection and ranging) -- the world's first optical radar designed for maritime search and detection – was recently incorporated as a payload in the SKELDAR V-200, a heavy fuel engine VTOL (vertical takeoff and landing) UAV (unmanned aerial vehicle) made by Swiss-based UMS SKELDAR.

  8. Gated Digital Holography Enhances LIDAR's Ability To See Through Obscuration

    The Naval Research Laboratory (NRL) has utilized a new technique to enhance the precision of LiDAR (light detection and ranging) instruments to see through objects and ground features obscured by foliage.

  9. Optical Phased Array Technology Could Make Lens-Based Cameras Obsolete

    Researchers at the California Institute of Technology (Caltech) have developed a 2D ultra-thin camera that uses an optical phased array (OPA), rather than the curved lenses and mechanical parts of a traditional camera, to capture images.

  10. New Virtual Reality Display Uses Optical Mapping To Ease Eye Fatigue

    A new type of 3D display being developed by researchers at the University of Illinois at Urbana-Champaign could pave the way for augmented reality (AR) and virtual reality (VR) headsets that do not cause headaches, nausea and eye fatigue symptoms commonly reported by users.
