ABSTRACT: Chalcogenide glass fibers are commercially available and are used for delivery of mid-infrared wavelengths (1.5um to 6.5um). These fibers allow compact, robust and low-weight laser platforms designs. Laser systems in high-power and high-stress environments find their reliability and performance limited due to free-space optical components. Free-space components suffer from vibration a ...

ABSTRACT: Scene generators are commonly used to create synthetic images of ground targets, such as tanks and battlefield wheeled vehicles, to facilitate seeker algorithm development.These scene generators can produce realistic output for sensor types such as infrared or radar, but are limited by the quality of the target models.Typically, the target models show little or no variation so that the s ...

ABSTRACT: Maintenance and sustainment are critical to structural integrity and availability of US Air Force aircraft.The first line of defense against corrosion is coatings and protection systems that provide barriers to the environment and inhibit corrosion of structural alloys.There are currently no methods or monitoring techniques to assess protection system condition, corrosive ingress into ai ...

ABSTRACT: Coatings on large aircraft undergo significant flexure, creating corrosion sites at seams and fasteners due to the formation of paint bridges on the substrate. Current coatings in use are based on polysulfide chemistry, contain chrome inhibitors, and do not consistently meet flexibility requirements of MIL-PRF-32239A. Luna will develop a next generation chrome-free flexible primer based ...

The state-of-the-art in infrared scene projection uses micro-machined resistor arrays. While a proven technology, these arrays are limited in frame-rate and dynamic range, and can be prohibitively costly as array size increases. Alternative technologies ...

ABSTRACT:Materials utilized for 3-5 micron IR optics, have historically been limited to chalcogenide glasses and semiconductor crystals because organic polymers are strongly IR absorbing in this regime, due to the presence of carbon hydrogen (C-H), or other carbon-heteroatom (C-X) vibrational modes. Polymers are still desirable for these applications because they can be readily processed/molded an ...

ABSTRACT: Echo Ridge proposes to design and performance characterize an LPI/LPD PNT augmentation system (including beacons and user equipment) using a hybrid frequency hopping, spread spectrum signal-based waveform which we believe can achieve compliant performance in ground applications.We have chosen this waveform class for its unique combination of PNT performance and low probability of interce ...

ABSTRACT: The Air Force needs an external, self-powered, non-invasive, RFID-like status monitoring device to track the handling and environmental factors experienced by missile armaments during its lifetime. Few current missile armament monitoring systems have the capability to monitor environmental conditions and use that data to determine time spent in storage, on the flightline, on the aircraft ...

ABSTRACT: Graf Research will research and develop optimal strategies for cloud-based trust assessment.We anticipate creating not only a novel cloud architecture that can facilitate the use of many of the DARPA-sponsored custom microelectronics trust software tools but also a unique, cloud-hosted software productOpTrust-Cwhich will devise optimal strategies for the proper implementation of defensiv ...
