Laser tech allows for longer-distance sensing

The trouble with existing 3D imaging technology is that – at the consumer level, at least – it tends to struggle with distances beyond a few feet. Put even a third of the width of a basketball court between yourself and a Microsoft Kinect sensor, for instance, and it won't pick up your movements at all. Researchers at the University of California, Berkeley, claim to have developed a Lidar (light radar)-based system that can remotely sense objects across distances as long as 30 feet (10 m), which could have widespread benefits in fields as diverse as entertainment, transportation, robotics, and mobile phones.Read More

Lasers could significantly shrink size and cost of particle accelerators

Particle accelerators like the Large Hadron Collider (LHC) are wonders of modern engineering and vending machines for Nobel prizes, but they’re also large – as indicated by the LHC's name – and costly. A new theoretical study by the Lawrence Berkeley National Laboratory's Berkeley Lab Laser Accelerator (BELLA) Center suggests how lasers could dramatically shrink the size and cost of particle accelerator. If the models hold true, it could remove a significant bottleneck from physics research and open up such machines to industrial and medical applications.Read More

Low-power laser triggers stem cells to repair teeth

Ranking among the X-Men probably isn't all that it's cracked up to be, but who wouldn't want their uncanny ability to regenerate lost bone or tissue? New research into tooth repair and stem cell biology, from a cross-institution team led by David Mooney of Harvard's Wyss Institute, may bring such regeneration one step closer to reality – or at the very least, give us hope that we can throw away those nasty dentures.

Shape-changing mirror puts lasers in focus

One cinematic cliché we've all seen is when the hero deflects the villain's dastardly laser beam with a hastily snatched hand mirror, sending it back at his adversary. Physics, ever the wet blanket, says that this is a highly improbable scenario. Focusing high-powered lasers isn't easy. A powerful laser distorts the mirror, throwing the beam off and spreading it out uselessly. To combat this, Fraunhofer is developing a lens that can deform itself to compensate for heating and other distortion factors to keep lasers focused on target.Read More

Laser weapon adds sea-going craft to its list of conquests

Lockheed Martin’s ADAM (Area Defense Anti-Munitions) High Energy Laser (HEL) system is part of a growing breed of high-energy weapons being developed for the armed forces of the near future. Having previously demonstrated its ability to track, target, and destroy rockets at high speed and at distances of up to 2 km (1.2 miles), the versatility of the ADAM system has been further established by taking aim at waterborne targets, successfully disabling a military-grade boat in a test on May 7 in the Pacific Ocean.Read More

DPI details 10,000 lumen laser projector ahead of July release

Digital Projection International (DPI) has announced the forthcoming release of what's claimed to be the first production high-brightness laser projector in the world. The low maintenance HIGHlite LASER WUXGA 3D delivers 10,000 lumens from a stable solid state illumination system rated for over 20,000 hours, which negates the need for regular lamp replacement cycles.Read More

Open-source Skirmos aims for advanced laser tag gameplay

From Pong, to 2D platforms and onto online first person shooters, our desire for an increasingly realistic gaming experience was always going to see platforms emerge where we combat our friends, foes and flesh-eating zombies using our real-world bodies. Skirmos, the latest take on the laser tag system, uses gun-mounted LCD display, radio-based dynamic scoring and open-source programming in an attempt bring the complex and varied experience of the modern multi-player shooter to life.
