Lunar Orbiter Lasers Mona Lisa to Moon
|
|
NASA's next moon mission has the acronym LADEE (Lunar Atmosphere and Dust Environment Explorer), but they've already sent a lady to the moon - or at least the image of one. Using a precisely timed laser, scientists at NASA's Goddard Space Flight Center have beamed an image of Leonardo da Vinci's masterpiece, the Mona Lisa, to the Lunar Orbiter Laser Altimeter (LOLA) instrument on the Lunar Reconnaissance Orbiter (LRO) orbiting the moon. The famous face traveled nearly 240,000 miles in digital form from the Next Generation Satellite Laser Ranging station at NASA Goddard, the first demonstration of laser communication with a satellite.

Image Compressor Beats JPEG
|
|
Unlike jpeg algorithms, which compress an image after it is taken, a new low-profile metamaterial sensor developed at Duke University uses microwave imaging to compress pictures as they are being recorded.

Nanowire Solar Cells Soak Up Sunlight
|
|
A team at Lund University is first to show that it is possible to use nanowires to manufacture solar cells. Such nanowires created from indium phosphide show potential for drastically improving cell efficiency and cost.

Optical Projection Moves from VIS to IR
|
|
A new imaging method enables optical projection tomography to be extended from the visible to the near-IR spectrum, something that could be used to study insulin-producing cells in diabetics, scientists at Umeå Center for Molecular Medicine in Sweden report.

Active and Passive Modes in One IR Camera
|
|
A new approach that integrates active and passive infrared imaging capability into a single chip paves the way toward lighter, simpler dual-mode active/passive cameras with lower power dissipation, say its creators at Northwestern University’s Center for Quantum Devices.

Real-time Profiling for Focusing, M2, Divergence & Alignment
DataRay Inc.
Beam intensity profiling is an essential tool in many aspects of photonics. The precise intensity distribution in a focused laser beam is critical in many applications: flow cytometry, laser printing, medical lasers, and cutting lasers are just a few examples. Intensity profile measurements can characterize and improve a product or process, leading to substantial cost and time savings that can pay for the measurement instrument many times over. This white paper describes how the unique, patented, real-time multiple z-plane XYZTF capabilities of the BeamMap2 slit-scan profiler can speed and simplify laser assembly alignment.

Photonics West 2013 - February 2 - 7, 2013 · San Francisco, CA
Visit us at BIOS Booth 8600 and Photonics West Booths 600 & 601
|
|
Photonics West 2013, to be held at the Moscone Center, will feature more than 4450 technical presentations, 18 plenary talks, 40 technical events and 70 continuing education accreditation short courses. The technical conferences - up about 5 percent over last year - are organized around four symposia: BiOS (Biomedical Optics), LASE (Lasers and Applications in Science and Engineering), OPTO (Integrated Optoelectronic Devices) and MOEMS-MEMS (Micro- and Nanofabrication). A virtual symposium on Green Photonics also will be held. The trade show and conference kicks off with BiOS, where the latest optical and photonic technologies used in diagnostics, therapeutics, and imaging are presented and discussed.
