Random Lasers Fight Noise, Improve Imaging
NEW HAVEN, Conn., May 1, 2012 — A new random laser illumination source for medical imaging equipment could improve the clarity and processing time of images, advancing the fields of microscopy and endoscopy.
Nanomaterial Yields Many Laser Colors
PROVIDENCE, R.I., May 1, 2012 — Nanocrystals that can produce red, green and blue laser light from a single material could open the door to digital displays and other devices that employ a variety of laser colors all at once.
Hitting Every Angle with Autostereoscopic 3-D Displays
May 1, 2012 — Clever use of electro-optics, lens arrays, diffusers and software advances the multidimensional way of seeing The broad field of autostereoscopic display – the creation of imagery that appears three-dimensional without requiring the use of...
Time Delay Integration Speeds Up Imaging
May 1, 2012 — Using a sensor architecture that permits photoelectrons generated from multiple exposures to be summed with no additive noise enables high-speed imaging under light-starved conditions. This technology has become a standard in the automated...
Wafer-Etching Process Brightens Future for LEDs
May 1, 2012 — With far higher etch rates and per-unit cost savings, high-temperature wet etching of sapphire wafers is giving dry etching a run for its money. LED manufacturers today can choose between two very different manufacturing processes. Dry etching...
193-nm Lithography Opens Doors for Diffractive Micro-Optics
May 1, 2012 — Design considerations and fabrication affect performance for a near-IR large-angle homogenizer for use in 3-D sensors based on time of flight. The field of diffractive micro-optics is playing an increasingly important role in today’s...
Vision Software Enables NASA Robonaut to See
May 1, 2012 — The first robotic visitor to the International Space Station performs difficult visual and tactile tasks in service to the human crew. The first humanoid robot astronaut boarded the International Space Station (ISS) in August 2011. Mission STS-133...
How to Develop a Laser Safety Culture
May 1, 2012 — What is the most important measure of a laser safety program’s success? Developing a true culture of laser safety is the ultimate goal of any serious laser safety officer. The art of inspiring and coordinating people’s activities beyond...
Transfer Technology and Grow
May 1, 2012 — CLEO:2012 is right around the corner, and Photonics Spectra will be there. This year, we are proud to be the media sponsor for the annual Technology Transfer Program, which will take place on Thursday, May 10. We have attended this event each year...
Alexander Graham Bell, we can hear you now
May 1, 2012 — Linguists, historians and even musicians could benefit from noninvasive optical scanning technology that enables us to hear voices and sounds that were recorded more than a century ago. Unlocking these sounds is part of a collaborative sound...
Supercapacitors created from laser-scribed graphene
LOS ANGELES – A novel graphene-based electrode, produced with a standard LightScribe DVD optical drive, ends the search for an optimal electrochemical capacitor. The discovery could pave the way for a new class of flexible energy-storage devices. ...
Hidden 3-D objects imaged
CAMBRIDGE, Mass. – A new ultrafast time-of-flight imaging technique uses reflections from a nonmirrored surface to recover 3-D shapes hidden from sight, essentially allowing the camera to capture images around corners. Scientists at MIT’s Media Lab...
Star comb aids search for exoplanets
BOULDER, Colo. – A new laser frequency comb soon may be able to answer one of the most intriguing scientific questions: Are there other earthlike planets in our galaxy capable of supporting life as we know it? A collaboration of the National Institute of...
Tsunami mapped with laser scanners
SENDAI, Japan – Using eyewitness video and terrestrial lasers to map the epic March 2011 Tohoku tsunami could produce flooding forecasts that influence future evacuation plans and building designs and could help prevent disasters of similar magnitude from taking...
Camera captures atoms moving in a molecule
COLUMBUS, Ohio – The first real-time image of two atoms vibrating in a molecule was recorded with a new ultrafast camera. A team from Kansas and The Ohio state universities used ultrafast laser pulses to knock one electron out of its natural orbit in a molecule, and...
Microlens arrays from a test tube
POTSDAM, Germany – Simple calcium carbonate precipitation at ambient conditions can produce microlens arrays of uniform size and focal length. The process offers a cheaper alternative to lithographic techniques used to create inorganic-based materials. Scientists...
Lab lightning strikes same place more than twice
PALAISEAU, France – With the help of a laser-based lightning rod, laboratory-generated lightning was coaxed to strike the same place not just twice but numerous times, and contrary to the path of least resistance. This advance demonstrates the potential of such rods...
Attosecond laser takes aim at “holy grail” of chemistry research
LONDON – Ultrafast pulses of laser light fired at oxygen, nitrogen and carbon monoxide molecules could pave the way toward imaging the movement of atoms and their electrons as they undergo chemical reactions – one of the holy grails of chemistry...
