Award Data

The nature and requirements of military operations lead to high noise levels, exposing military and civilian personnel to the possibility of noise-induced hearing loss. Otoacoustic emission (OAE) probes can assess the health of the inner ear by testing the response of the cochlea to various types of stimuli. The measurement of emissions at high frequency has the potential to detect noise-induced d ...

In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

Optonicus proposes development of the Wide-Area Laser Additive Manufacturing in Metals with Adaptive Beam Shaping (WALAM-ABS) laser additive manufacturing (LAM) system. The WALAM-ABS metal additive manufacturing system will solve long-standing drawbacks imposed by current single-point selective laser melting LAM technology through the use of wide-area processing based on proprietary multi-beam fib ...

Modern Directed Energy (DE) missions require target engagements at low elevation angles and long ranges.These engagement geometries require propagation through distributed-volume turbulence. To correct for distributed-volume turbulence effects, an estimation of the turbulence along the propagation path is required. Correcting for these image aberrations will improve the quality of the target image ...

Nutronics, Inc. and Montana State University propose to develop and evaluate computational methods for a Volume Digital Holographic Wavefront Sensor (VDHWFS).VDHWFS based imaging offers the potential to provide the equivalent of wide field of view adaptive optics (AO) compensated imaging, but without the added complexity of AO components and hardware.Recent result for coherent imaging developed by ...

QmagiQ and MIT-LL propose to partner to develop a very longwave infrared (VLWIR) digital focal plane array (DFPA) and camera for imaging spectroscopy applications. The DFPA will be based on Type-II InAs/GaSb strained layer superlattice (SLS) photodiodes with>13 micron cutoff, hybridized to a 640x480 digital readout integrated circuit (DROIC). In Phase I , QmagiQ will develop a 13 micron cutoff d ...

This Small Business Technology Transfer Phase I project will develop ultradense, low-power plasmonic integration components and devices for on-chip manipulation and processing of optical signals. Both passive and active components will be studied. Detailed performance predictions will be obtained through finite element modeling (FEM) of the harmonic Maxwell’s equations. The FEM provides detai ...

The design of future hypersonic vehicles requires detailed understanding of flow regimes ranging from rarefied to continuum. Hypervelocity flows are characterized by high temperatures, real gas effects, nonequilibrium chemistry, and ionization. The goal of this project is to develop unified kinetic/continuum solution methods with automatic domain decomposition for a wide range of Air Force applic ...

This proposal addresses the requirement to significantly improve the affordability, maintainability and performance of KKV DACS components. Exothermics and their Phase 1 partner Southern Research Institute will endeavor to increase the performance, lower the cost and enhance the technical property characteristics of SDACS and hypersonic components by examining the use of a new class of ultrahigh t ...

Higher efficiency solar cells are needed to reduce solar array mass, volume, and cost for Air Force space missions. Intermediate-band quantum-dot (QD) solar cells can yield dramatically higher efficiencies than current multi-junction (MJ) technologies. However, several issues must be addressed to demonstrate manufacturable, high efficiency devices. CFDRC aims to develop: 1) High-efficiency, ligh ...
