Branimir Blagojevic, Technologist, Goddard Space Flight Center, Greenbelt, MD

During his time with former employer Science and Engineering Services, LLC, Branimir Blagojevic helped build a remote-sensing device that detected biological agents. The technology, originally made for the Department of Defense (DoD), may soon find a place on Mars. Blagojevic currently leads the development of the Bio-Indicator Lidar Instrument (BILI), a device that could be used to spot organic molecules and signs of life on Mars.

Will touchscreens take over the dashboard?

This week's Question: With backup cameras now mandatory in today's vehicles, screens in cars are increasingly becoming a standard feature. At the Consumer Electronics Show in Las Vegas this month, Corning Glass presented a demo of a new kind of automotive interior — one making full use of touch-based smart glass, from the windshield to the console. A head-up display built into the driver's side, for example, provided on-windshield navigation; a smart screen in the steering wheel provided access to all of the car's controls; and a full video display enabled passengers to watch videos. The maker of "Gorilla Glass," used in the latest iPhone, envisions a future a where a driver's dashboard will be entirely screen-based. What do you think? Will touchscreens take over the dashboard?

Researchers Awaken Graphene's Hidden Superconductivity

Since its discovery in 2004, scientists have believed that graphene contained an innate ability to superconduct. Now researchers from the University of Cambridge have found a way to activate that previously dormant potential, enabling the material to carry an electrical current with zero resistance.

Laser Diode Modules

BEA Lasers (Elk Grove Village, IL) has introduced two new low-profile additions to their rugged MIL Series of laser diode modules. The new MIL RA Model features a right angle, and the new MIL Compact Model features a straight housing. Both new models utilize a low profile 3/8” rugged laser housing, fitted with a M12 connector, 2 meter long PVC jacketed cable, and integrated power supply. The optional sensor-style bracket, or multi-adjustable “LB” bracket, completes the laser system. The new MIL Series laser diode modules are offered with standard 515nm (green) or standard 635nm (red), with 1mW or 5mW.

Time-to-Digital Converter

Mouser Electronics, Inc., (Mansfield, TX) is now stocking the TDC7201 time-to-digital converter from Texas Instruments (TI). The TDC7201 is designed for use with ultrasonic, laser, and radar range finding equipment using time-of-flight (TOF) technique. TI’s TDC7201 time-to-digital converter has two built-in time-to-digital converters (TDCs) that can be used to measure distance down to 4 cm and up to several kilometers using a simple architecture. The TDC7201 features a wide measurement range of 0.25 ns to 8 ms and high accuracy of 28 ps. The device has a single shot resolution of 55 ps, (equivalent to 0.825 cm).

Single Photon Counting Module

Excelitas Technologies® (Waltham, MA) has introduced SPCM-NIR, a Single Photon Counting Module specifically selected and performance-optimized for the near-infrared (NIR) wavelength spectrum. This NIR-spectrum enhanced device is designed to support long-range LIDAR, quantum communication and microscopy applications. The Excelitas SPCM-NIR uses a specially selected silicon avalanche photodiode (SLiK) with peak single photon detection efficiency (PDE) at 780nm, typically better than 73%, while maintaining uniformity over a 180 μm diameter active area.
