Diode laser present one of the most challenging thermal problems in industry. The small footprint and very high power levels combine to create extremely high heat fluxes in the vicinity of the diode. Tese heat flux levels raise the diode temperature,leading to lower lasing efficiency, wavelength shifts, and reduced diode lifetime. The cooling problem becomes even more difficult when combined wi ...

The objective of the proposed research is to develop both an advanced design methodology and an innovative process for designing and manufacturing novel composite materials for future military air vehicles. The proposed new design methodology, referred toas function-oriented material design (FOMD), will provide an effective tool for the optimal design of structurally efficient composites, such as ...

A novel method of intraweapon wireless communications using magnetic field transmissions was demonstrated during the Phase I portion of this program. Normal physical wire communication links cannot be expected to survive during and after targetpenetration. Therefore, various methods of wireless communication within a metal cylinder 15 inches in diameter and 10 feet in length were evaluated and c ...

This Small Business Innovation Research (SBIR) Phase I project will develop a magnetic microarray reader that, as part of a magnetics-based bioassay technology, addresses mass consumer applications for microarrays. Magnetic labels as reporters in DNA and immunoassays have already shown excellent sensitivity. Previous versions of magnetic DNA arrays perform DNA and immunoassays directly on the ma ...

This Small Business Innovation Research (SBIR) Phase II Project proposes to develop an innovative solution to the the problem of chlorinated solvent contamination in variably saturated, low permeability soils. Prior Phase I work has demonstrated that: 1) chitin is an effective electron donor for stimulating biodegradation of chlorinated solvents, 2) that chitin enhances bioavailability of the so ...

Flash laser radar (ladar) systems have been developed for automatic target identification in military surveillance systems. Ideally, the system is able to distinguish pixels containing the target from pixels containing background. A signal processor thenuses the range value at target pixels to estimate the target's 3-D shape (angle-angle-range) and, from the 3-D shape, identify the target. Howe ...

We propose to develop the design for a terahertz imaging and spectroscopy inspection system prototype for the detection of concealed threats in packages and personnel. Terahertz imaging has the potential to reveal concealed explosives; metallic andnon-metallic weapons (such as ceramic, plastic or composite guns and knives); flammables; biological agents; chemical weapons and other threats hidden ...

This Small Business Innovation Research (SBIR) Phase I project will perform research aimed at characterizing subsurface residual stresses induced through surface treatments in single crystal and complex polycrystalline materials. Photon Induced Positron Annihilation (PIPA) will be used to quantify subsurface residual stress in single crystal materials and operational components subjected to high s ...

This Small Business Innovation Research (SBIR) Phase I project aims at developing diagnostics for liquid fuel combustion systems. The proposed instrumentation will provide a noninvasive measurement of liquid volume, surface area and velocity within a cross-sectional plane of the dense spray. The technique is applicable to burning and non-burning sprays and is equally effective for spherical and no ...
