Current scene projection hardware is challenged to simultaneously meet the requirements for high peak temperature (> 2000K), high resolution (2Kx2K), response time < 4 ms, cryogenic and temporally uniform photon flux. MEMS, Resistor arrays, liquid crystals, and photonic crystals all suffer in one or more areas. MEMS suffer from flicker and low dynamic range. Resistor arrays suffer from low frame r ...

The performance of a composite material is heavily influenced by the strength and toughness of the interlaminar region, which is the resin rich area between the plies of a fiber reinforced composite.  The interlaminar region generally provides a direct path for crack propagation since no continuous reinforcement is present and is often the cause of failure in materials subjected to cyclic loadin ...

The purpose of this Phase II project is to develop computational modeling methods that are able to describe the propagation and interaction of fatigue cracks using the phase-field methodology within the numerical framework of isogeometric analysis (IGA). The resulting computational platform, while focused on fracture and fatigue, will be general, in that any phase-field method can be easily incorp ...

Naval aircraft components are routinely made of 7000 series aluminum alloys due to their strength, weight and fatigue properties. Present Additive Manufacturing (AM) processes fall short of producing 7000 series Al alloys successfully due to lack of porosity, and thermal and composition control. In-situ methods implemented to date largely only yield information about the component surface and othe ...

This Phase-II STTR proposal proposes the use of a new class of diamond-seeded solid-state material system for the manufacture of virtually all packaged intense heat-generating solid-state electronics in X-band and Ballistic Missile Defense radar components and systems. In this proposal wherein much preliminary (also MDA-funded) work has been demonstrated hitherto by the authors, Gallium Nitride-on ...

This project addresses the U.S. Air Force needs for single-piece, electronically dimmable eye protection device (EDEPD). Toward demonstrating the proof-of-principle, InnoSense LLC (ISL) in Phase I developed and evaluated individual layer components and their stacked structures. ISL also demonstrated the fabrication processes for individual-layer components, stacked structures and the scale-up pote ...

We propose a compact, monolithic, power scalable, hollow core fiber-gas laser emitting in the atmospheric transmission region in the mid-IR, titled "mid-IR ATLAS." The proposed optically pumped fiber-gas laser system is efficient, has a small footprint as well broad spectral coverage in the mid-IR. Due to the unique approach employed, the proposed technology allows generation of mid-IR output with ...

Advanced imaging techniques and, novel intelligence, surveillance and reconnaissance (ISR) methods are of great interest to the U.S. Air Force and other Department of Defense (DoD) agencies, but associated high-costs of III-V and II-VI MWIR and SWIR materials prohibit their practical widespread deployment and integration with other optoelectronic devices. In this program, we intend to investigate ...

A prototyping effort is being proposed to develop methods and tools for utilizing structures of opportunity as efficient radiations in the HF, VHF and UHF bands.

BaySpec Inc., in collaboration with Pacific Northwest National Laboratory, proposes to develop a new portable multi-order mass spectrometry system that can sequence peptides derived from biological agents including bacteria, viruses, and toxins. During Phase I stage, a fully functional prototype instrument, based on an innovative design concept, was successfully built and the performance evaluatio ...
