‘Groovy’ hologram creates strange state of light at visible and invisible wavelengths
Nanostructured device controls the intensity, phase, and polarization of light for wide applications in optics Cambridge, Mass. – August 20, 2013 – Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated with nanoscale […]
Advancing resistive memory to improve portable electronics
Researchers develop novel way to build resistive memory devices that could become the storage part of the next generation of smart phones and tablets RIVERSIDE, Calif. — A team at the University of California, Riverside Bourns College of Engineering has developed a novel way to build what many see as the next generation memory storage […]
Digital streak camera captures full-color photographs of high-speed objects
Optical Engineering article details device and innovation process LAGUNA HILLS, California, USA — Researchers at MetroLaser, Inc., have developed a new design for a digital streak camera that captures full-color images of projectiles traveling up to 3350 m/s, which is 10 times the speed of sound. This system was designed to replace the outdated film-based […]
Researchers slow light to a crawl in liquid crystal matrix
New technique could find uses in highly sensitive interferometers and other measuring device WASHINGTON, Aug. 13, 2013—Light traveling in a vacuum is the Universe’s ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed bump in light’s path. Reported today in The […]
University of Tennessee professors study dilemmas in sustaining red light camera programs
It’s a common driving predicament: As you approach the intersection, the light is yellow. Do you hit the brakes or face a red light camera fine? Some municipalities engineer their traffic signals to force drivers into this situation in an effort to generate revenue from the cameras. Professors at the University of Tennessee, Knoxville, have […]
Waterproof LED drivers provide expanded functionality in a variety of outdoor applications
Phihong USA has expanded its PDA072 and PDA080 constant voltage LED driver series with 0-10V dimming models. The new PDA072 Series addition, designated the PDA072W-24VG-R, is rated for outputs of 72W at 24VDC and the new PDA080 Series addition, designated the PDA080W-48VG-R, is rated for outputs of 80W at 48VDC. Both the PDA072 and PDA080 […]
Reducing multitasking at HP Digital Camera
Like many consumer electronics organizations, HP Digital Camera saw that its people were working hard, but they also knew that they were not meeting deadlines and were not as productive as they needed to be. In the year before implementing the steps necessary to eliminate organizational multitasking, HP Digital Camera had released six different models […]
Researchers overcome technical hurdles in quest for inexpensive, durable electronics and solar cells
University of Minnesota engineers discover novel technology for producing “electronic ink” MINNEAPOLIS / ST. PAUL (07/30/2013) —Electronic touch pads that cost just a few dollars and solar cells that cost the same as roof shingles are one step closer to reality today. Researchers in the University of Minnesota’s College of Science and Engineering and the […]
New techniques use lasers, LEDs, and optics to ‘see’ under the skin
Special section in the Journal of Biomedical Optics BELLINGHAM, Washington, USA – Impressive examples of new non-invasive optical techniques using lasers, light-emitting diodes (LEDs), and spectroscopic methods to probe and render images from beneath the surface of the skin are featured in a newly completed special section in the Journal of Biomedical Optics published by […]
