NIR Single Photon Counting OEM Module

AUREA Technology (Besancon, France) has launched its newly designed fast Near Infrared (NIR) [900 nm-1700 nm] Single Photon Counting OEM Module, SPD_NIR_OEM_120MHz. Due to its Geiger-mode InGaAs avalanche photodiode SPAD and its new enhanced embedded electronics, it provides gated-mode operation up to 120 MHz trigger rate with very fast timing resolution < 150 psec. The SPD_NIR_OEM_120MHz performs very-low-noise DCR www.aureatechnology.com

Pyroelectric Detectors

LASER COMPONENTS Pyro Group (Olching, Germany) produces pyroelectric DLaTGS detectors - three series are available: One for users who would like to combine their detectors with their own electronics (LCDT-5000 series); the LCTDT-5100 series is designed for low-fre¬quency applications in the range of 10-100 Hz, and the LCDT-5500 type with a low-noise JFET is designed for FTIR applications. All detectors possess thinned-out ele¬ments and optionally feature an absorbing black coating with a low thermal mass that offers a wide spectral response at a simultaneously high speed. All pyrodetectors are available with different diameters of their active surfaces and rectangular and square shapes as well. Standard housings include TO-5, TO-66, and TO-37. www.lasercomponents.com/de-en/ir-components/ir-detectors/pyroelectric-sensors/

Four-Channel Intelligent LED Controllers

Saelig Company Inc. (Fairport, NY) has announced the LED-Warrior04, a 4 channel, intelligent, programmable LED constant-current driver with DALI, DMX512, and I2C interfaces on board. Other bus protocols or wireless options can be added via the I2C interface. For each of the four channels, the forward current and brightness of the LEDs can be individually and independently programmed. Current can be programmed from 80 mA to 1000 mA in 5mA steps. Brightness is controlled by internal 12-bit PWMs for each channel, allowing 4096 steps, with dimming down to 1/4096 or 0.024%. The high resolution of brightness control allows precise color mixing or calibration of multiple LED groups. The four 12-bit channels allow up to 281 trillion color hues. www.saelig.com

Products of Tomorrow: February 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

NACA to NASA: 100 Years of Aeronautics Innovation

Streamlined aircraft bodies, quieter jet engines, techniques for preventing icing, drag-reducing winglets, lightweight composite structures, and so much more are an everyday part of flying thanks to NASA research that traces its origins back to the earliest days of aviation.

NACA Technology: Then and Now

“Be patient, if you want to see the concrete benefits of space research. I am confident that the benefits are there. We at NASA have been given a big job— planning and executing the nation’s civilian space program. But I would first like to dispose of a question that is asked of me quite often: Why venture at all into the unknown, towards the Moon, the planets, and then towards the stars so far beyond? One answer was given by Tsiolkowsky, the 19th century scientist who Russia considers the grandfather of space. It was that the Earth is the cradle of the mind, but one cannot live forever in a cradle.”

Tech Briefs Interview: NASA’s Kathy Lueders

At the annual meeting of the Society of Automotive Engineers (SAE) in Detroit on January 14, 1959, NASA’s first Administrator, Dr. T. Keith Glennan, said: “I can imagine a remote future when spaceflight, in some form, might become nearly as commonplace as air travel is today.”
