2014/03/04 Compact, High-Power and Efficient Ultraviolet Laser for BioChem Detection
Raman spectroscopy uses lasers to measure molecular vibrations to quickly and accurately identify unknown substances. Ultraviolet (UV) lasers have the optimal wavelength for Raman spectroscopy at stand-off distances, but the Defense Department’s (DoD) current UV-based tactical detection systems are large and expensive and have limited functionality. A new DARPA program seeks technology that may make UV-based detection equipment more readily available in the field.
2014/03/06 MUSE Envisions Mining “Big Code” to Improve Software Reliability and Construction MUSE seeks to leverage deep program analyses and big data analytics to create a public database containing mined inferences about salient properties, behaviors and vulnerabilities of software drawn from the hundreds of billions of lines of open source code available today. The program aims to make significant advances in the way software is built, debugged, verified, maintained and understood, and to enable the automated repair of existing programs and synthesis of new ones.
2014/03/06 Excalibur Prototype Extends Reach of High-Energy Lasers High-energy lasers (HEL) have the potential to benefit a variety of military missions, particularly as weapons or as high-bandwidth communications devices. However, the massive size, weight and power requirements (SWaP) of legacy laser systems limit their use on many military platforms. Even if SWaP limitations can be overcome, turbulence manifested as density fluctuations in the atmosphere increase laser beam size at the target, further limiting laser target irradiance and effectiveness over long distances.
