THE CONTRACTOR HAS PATENTED TECHNOLOGY FOR A UNIQUE PROCESS THAT DIRECTLY CONVERTS AN ACOUSTIC SIGNAL INTO A VISIBLE ONE IN REAL-TIME WITHOUT ELECTRONIC CIRCUITRY. THIS RELIES ON THE ACOUSTO-OPTICAL PROPERTIES OF A CONTINUOUS LAYER OF LIQUID CRYSTAL THIN FILM LAYER WHICH SERVES AS BOTH THE SENSOR AND THE DISPLAY. THE IMAGE CAN BE VIEWED DIRECTLY BY MEANS OF CCD CAMERA. HOLOGRAPHY PROVIDES FOR BOTH ...

The current distribution in plasma radiation sources is both a yardstick for measuring the coupling efficiency of the generator, and a means of studying the implosion dynamics of the load. Since the current distribution cannot be directly measured, it must be deduced from the magnetic field profile. Magnetic field distributions, based on the Faraday rotation of polarized laser light, are typical ...

Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...

The intensity ratio of forbidden-to-allowed transitions in Li and He have been used to determine both turbulent electric fields due to plasma instabilities and quasi-static applied electric fields in low density and temperature plasmas. HY-Tech proposes to extend this technique to the plasma temperatures and densities encountered in plasma radiation sources. In this case uv spectra of Li-like and ...

Materials and Manufacturing Systems, Inc. (MATSYS) proposes to develop novel reactive structural materials for the enhancement of munitions lethality. This effort will combine our unique expertise in instrumented-Hot Isostatic Pressing (HIP) with new approaches in intermetallic design to develop a new generation of cost-efficient, high strength and reactive composites. The proposed material syst ...

The objective of this proposal is to demonstrate the feasibility of utilizing a three-dimensional spatial display to visualize information from a time-varying hazard prediction model. A spatial 3D display offers true volumetric projections of data and allows observers to gain insight of hazard information that is not possible with conventional 3D graphical scenes on a 2D surface or with presented ...

OBJECTIVE: Develop a Forensic DNA Analysis Kit for Genetic Intelligence that can be used on unknown human DNA samples collected from the battlefield to provide information about the individual who deposited the sample, such as potential ethnicity, height, eye color, hair color, age, sex, and/or facial features. The kit should leverage Short Tandem Repeats (STR), Single Nucleotide Polymorphisms (S ...

Surface detection of specific radioisotopes of the noble gases xenon and argon are essential for detection and discrimination of underground nuclear explosions. We propose a unique combination of numerical modeling and stable isotope release experiments to enhance the predictability of subsurface transport of the noble gases of interest. Our proposed research will identify and quantify the physi ...

U.S. military communications and weapons systems are reliant on electronics systems that are highly sensitive to external electromagnetic (EM) threats, whether from intentional or environmental sources. In order to protect from these external EM threats, high levels of electromagnetic interference (EMI) shielding are required. Significant advances in materials technology and manufacturing, howev ...
