Multi-axis fiber grating strain sensors may be used to localize and qualitatively identify the degree of damage in composite parts. Signatures associated with delaminations and damage tow material are significantly different for strain imaging produced data. This Phase I project is directed toward improving the quantitative measurement capability of "strain imaging" methods through experiments, ...

Missile defense battle management is an inherently distributed process, involving sensors, weapons, and targets that are distributed over a region spanning thousands of miles. While most agents need some sense of "distant events", they neither need nor can afford detailed, high-fidelity models of the entire situation. CleverSet's approach to distributed battle management is based in variable reso ...

EOSPACE proposes to develop a Compact Array of Analog Modulators and Integrated Laser Source (CAAMILS) module for use in a wide-bandwidth analog ladar scene projection system. Under Phase I, EOSPACE used its unique, exceptionally low loss, lithium niobate (LiNbO3) integrated electro-optic waveguide technology to fabricate a practical and cost-effective, yet state-of-the-art, ultra-low-loss, high- ...

EOSPACE Inc. proposes to design and develop a very high-performance coherent Ladar transmitter with the key electro-optical components based on ultra-low-loss, broadband electro-optic lithium niobate waveguide technology, including very-high extinction ratio (>60dB), wide bandwidth (dc to > 1GHz) modulator for 1.06 microns wavelength of operation. An incorporation of optical polarization control c ...

We propose to define and develop state-of-the-art forecasting and nowcasting tools to support HAA operations. Our focus is on stratospheric gravity wave (GW) processes, turbulence, and transient luminous events (TLE) and related electrical discharges to altitudes of 70,000 feet. These phenomena currently threaten reconnaissance and targeting missions and in the case of GW and turbulence have resul ...

Birefringence microscopy provides a necessary tool for the next generation electro-optic components. This effort builds on the great success of the Phase I effort that demostrated a benchtop system that could measure birefringent samples with high spatial resolution (~1mm) and high accuracy (0.1m). From this basis we will develop an engineering prototype that meets the needs of industry and the mi ...

In this program, we propose to develop high-performance long-wavelength infrared (LWIR) photodetectors based on InAs/In(x)Ga(1-x)Sb Type II superlattice structures. The use of bandgap engineering approaches to control quantum confinement and strain effects allows for wide tunability of the superlattice bandgap, making these structures ideal for LWIR detection in the 8 to 12 um wavelength range. ...

The inability of current plume signature codes to accurately predict the altitude in the afterburning region at which the peak signature occurs and the rate of signature decay with altitude ("afterburning shutdown") is the subject of this solicitation. A more accurate description of afterburning plume chemistry is needed, particularly for hydrocsrbon-fueled systems. The issue is that either the ch ...

The impact of liquid fueled missile, thermal management systems on plume signatures, is of critical importance to accurate plume signature modeling. This proposal describes the innovative coupling of an engineering level thermal design tool, VITMAC (Vehicle Integrated Thermal Management Analysis Code) with a Quasi 3-D enhanced Standardized Plume Flowfield Model, SPF-IIIQ3D. In addition, we will ...

Radiation effects play a critical role in the performance and reliability of MDA systems. Recognizing this, radiation transport simulations are widely performed throughout the product design cycle. While Monte Carlo is widely used for these simulations, computational times can be excessive unless sophisticated variance reduction methods are employed. However, this process can be extremely difficul ...
