The proposed work will address the core physics underlying acoustic reverberation as related to properties of the ocean environment and properties of the acoustic sources, receivers and waveforms that make up ocean-going acoustic systems of interest to the U.S. Navy. Present day active acoustic system performance models, which contain reverberation models as an essential component, are over twenty ...

US troops and equipment are increasingly at risk for irradiation by lasers, whether it be from enemy targeting and ranging systems, designators, or high-energy lasers as weapons themselves. Countering the threat requires detection of the incident laser radiation, the direction from which it is originating, and characterization of its wavelength and temporal profile. Nanohmics Inc., in partnership ...

The proliferation of laser based weapons systems has led to the need for laser threat sensor systems that operate over wide spectral range from the visible to infrared and provide sufficient dynamic range to measure the irradiance levels seen in practice. OPTRA, Inc. proposes a solution based on the complementary combination of CMOS readout integrated circuitry and diffractive optics to provide th ...

The Navy is seeking a new light-weight Atmospheric Diving Suit (ADS) design. This suit must be less than 400 lbs; at this weight a diver will be able to self-propel using his legs and fins. The system must ensure the divers safety at a working depth of 1000 ft of sea-water; protecting the body from the high external pressure at depth, while providing a sustainable 1 ATM internal pressure. Mide in ...

UUV"s have become increasingly important tools in the collection of environmental data. Their unique ability to operate independent of surface vessel conditions allows artic measures when traditional means is not possible. It is now well agreed that artic regions are critical to man"s understanding of the environment. Historically sensor packages for UUV"s have been based on"adaptions"of ship depl ...

We envision a coherently coupled QCL array architecture featuring 2nd order DFB gratings to vertically couple out light with excellent beam quality and high output power. This approach does not require cleaving of the devices or facet coatings and is therefore inherently more robust and manufacturable than facet emitters.

The low weight, excellent durability and heat resistance of ceramic matrix composites (CMCs) make them attractive materials for use in aircraft engine hot sections, where improved overall engine efficiency can be realized. Nevertheless, the interlaminar properties of CMCs must be well understood before CMCs can realistically replace metallic superalloys in engine hot sections, and no standardized ...

The rare-earth elements (REEs) find uses in many high tech military applications, including night vision goggles, laser range finders, precision guided weapons, and stealth technology. Their high costs (up to $6800/lb. Scandium) are due to low concentration in ores and high cost of separation. Fourteen of the REEs are listed in a single box in the periodic table, meaning they all have almost iden ...

In this Phase I SBIR proposal, Reactive Innovations, LLC will demonstrate the technical and economic viability of a room temperature environmentally friendly technology for extraction and separation of light rare earth metals (lanthanides) with improved efficiency. Rare earths currently require multiple separation steps to yield high purity material. Decreasing the number of separation processes ...

Metal Oxygen Separation Technologies, Inc. proposes a 6-month SBIR Phase I project to demonstrate feasibility of using molten salt electrolysis with a zirconia solid electrolyte to cleanly and efficiently produce dysprosium metal from its oxide. This Phase I project will have as its goal the design of a molten salt-zirconia-anode system in the context of an electrolysis cell for producing high-pu ...
