The infrared (IR) spectrum is a vast information landscape that modern IR detectors tap into for diverse applications such as night vision, biochemical spectroscopy, microelectronics design, and climate science. But modern sensors used in these practical areas lack spectral selectivity and must filter out noise, limiting their performance. Advanced IR sensors can achieve ultrasensitive, single-photon level detection, but these sensors must be cryogenically cooled to 4 K (−269 C) and require large, bulky power sources making them too expensive and impractical for everyday Department of Defense or commercial use.

DARPA’s Optomechanical Thermal Imaging (OpTIm) program aims to develop novel, compact, and room-temperature IR sensors with quantum-level performance – bridging the performance gap between limited capability uncooled thermal detectors and high-performance cryogenically cooled photodetectors.

“If researchers can meet the program’s metrics, we will enable IR detection with orders-of-magnitude improvements in sensitivity, spectral control, and response time over current room-temperature IR devices,” said Mukund Vengalattore, OpTIm program manager in DARPA’s Defense Sciences Office. “Achieving quantum-level sensitivity in room-temperature, compact IR sensors would transform battlefield surveillance, night vision, and terrestrial and space imaging. It would also enable a host of commercial applications including infrared spectroscopy for non-invasive cancer diagnosis, highly accurate and immediate pathogen detection from a person’s breath or in the air, and pre-disease detection of threats to agriculture and foliage health.”

Google employees are ratcheting up pressure on the internet-search giant to abandon its artificial intelligence work with the Israeli government, planning public demonstrations to draw greater attention to the controversial cloud-computing contract.

A handful of current and former workers spoke on Wednesday alongside Palestinian rights activists in San Francisco to call for the Alphabet Inc.-owned company to end Project Nimbus, a $1.2 billion contract through which Google and Amazon.com Inc. provide the Israeli government and military with AI and cloud services. The seven-year contract went into effect in July 2021. A petition protesting the agreement has received 800 signatures from Google employees, according to one of the organizers.

WASHINGTON — The Defense Advanced Research Projects Agency said it selected teams to help develop an on-orbit satellite communications translator within just eight days of releasing a formal solicitation. Now, the Pentagon agency charged with making investments in transformational technology wants to apply that quick approach to other programs.

DARPA announced last month that 11 teams would participate in Phase 1 its Space-Based Adaptive Communications Node program, dubbed Space-BACN, an in-space terminal designed to help government and commercial satellites communicate.

The capability is increasing in relevance as companies such as SpaceX and organizations including the Space Development Agency launch large constellations of satellites to low Earth orbit, within 1,000 kilometers of the planet’s surface. Awardees range from universities to commercial companies, some of which have never worked with the U.S. Department of Defense. DARPA didn’t announce the total value of the agreements.

In the last three or four years, he said, “we’ve gone through three different versions of our dismounted gear. So we’re able to quickly pivot to the next technology and not necessarily go down long-term production of the same solution when the technology is iterating and the threat is iterating.”

The Army is reinvigorating its networks, sensors, EW arsenal and related tools following decades of counterterrorism operations — a period when troops engaged with forces sporting less-advanced gear and communications were less at risk.

The U.S. is now preparing for potential fights against China and Russia, two world powers that spend significantly on military science and technology. The targeting of networks and other battlefield systems seen in the Russia-Ukraine war is only adding to the sense of urgency.

While virtual reality has been around for decades, a combination of higher-resolution graphics, smoother tracking of the user’s movements and cheaper, sleeker headsets has propelled the immersive technology into arenas beyond gaming and military training.

Sounds like a sci-fi movie right? But it’s not. Naval Surface Warfare Center, Philadelphia Division is testing laser-based sensors on robot dogs or drones as a way to perform battle damage assessment, repair, installation, and modernization – all remotely.

NSWCPD’s Advanced Data Acquisition Prototyping Technology Virtual Environments (ADAPT.VE) engineers and scientists are testing new applications for light detection and ranging (LiDAR) to build 3D ship models aboard the ‘mothballed’ fleet of decommissioned ships at the Philadelphia Navy Yard.

Two of America’s top chipmakers have been ordered to stop selling some of their technology to China that can be used for artificial intelligence.

Nvidia (NVDA) and AMD (AMD) said Wednesday that they had been told by the US government to halt exports of certain high-performance chips to the world’s second largest economy.

In a regulatory filing, Nvidia said that it had been told by US officials that the requirement was due to a potential risk of the products being used by, or diverted to, a “military end user.”
