New Products — March 2017 Photonics & Imaging Technology

Near Eye Displays Test SystemA new test system from Gamma Scientific (San Diego, CA) offers high spatial resolution color and contrast measurements for near eye displays (NED), such as virtual reality (VR) and augmented reality (AR) headsets, and heads up displays (HUD). The Gamma Scientific NED Measurement System incorporates compact imaging optics which feed both an integrated camera viewing system and a low-noise, high-accuracy spectroradiometer.

Large-Area, Polarization-Sensitive Bolometer for Multi-Mode Optics

This type of detector will be used by the PIXIE mission to map the microwave sky in polarization, opening a new window to the earliest moments of the universe. Polarization-sensitive bolometer measures linear polarization of the cosmic microwave background. (Left) Prototype detector. The absorber in the central square fills a small fraction of the optical area, but is opaque to microwaves. (Center) Schematic diagram showing the absorbing wires and sensing thermistors. (Right) Photomicrograph showing absorbing wires and the crystalline silicon end bank. Measurements of the cosmic microwave background are a powerful probe of the early universe. Part-per-million fluctuations in the intensity of background trace the initial conditions of matter and energy shortly after the Big Bang, mapping the large-scale structure of spacetime. Now, new measurements in linear polarization at sensitivities of a few parts per billion can look behind these initial conditions to test physics at energies a trillion times higher than terrestrial accelerators, and perhaps even provide a glimpse of quantum gravity in action.

Autonomous Driving — In a ‘Flash’

By combining CMOS technology with avalanche photodiodes, researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS (Duisburg, Germany) have developed a potentially cost-effective sensor prototype that aims to support driverless car applications. The “Flash LiDAR” could play a valuable role alongside the cameras, radars, and other components within autonomous vehicles.

Infrared Cameras Support Advanced 3D Printing Efforts

Additive manufacturing (AM), also known as 3D printing, is quite literally one of the most innovative technologies revolutionizing manufacturing today, in terms of both industry “buzz” and thermal properties. Unlike subtractive manufacturing methods such as machining, the growing range of AM technologies creates components directly from a computer model, adding material only where needed. Wohlers Associates, a leading independent consulting firm focused on these technologies, is forecasting that the value of the worldwide AM market will grow to more than $10.8 billion by 2021, up from just $2.2 billion in 2012. That rapid escalation, however, isn't the result of hobbyists buying desktop 3D printers that cost a few hundred dollars.

Wireless Tamper Detection Sensor and Sensing System

The sensors can detect and locate cracks, material strain, or impact damage.NASA's Langley Research Center researchers have developed a wireless, connection-free inductor capacitor sensor system that can be placed on or embedded in materials and structures to monitor for and detect damage. The sensors can also be used to detect package tampering and pilfering. This innovation — SansEC (Sans Electrical Connections) — makes sensors more damage resilient and more environmentally friendly to manufacture and use.

CERTIFICATES AND SIGNATURES: How to Ensure Authentication in the IoT

On October 21, 2016, the Internet saw a significant distributed denial of service (DDoS) attack, conducted via a botnet comprising many co-opted Internet-connected devices. The attackers of the network infrastructure were able to control these Internet-of-Things (IoT) devices for a number of reasons, including a lack of strong authentication. Loaded software turned the machines into puppets that interfered with Internet traffic for millions of users.
