This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II ...

To achieve the goals of this program improving spectral coverage and output power of monolithic QCL sources - we propose to develop in collaboration with MIT Lincoln Laboratory a broadly tunable high power source that is based on Eos proprietary QCL array technology. The current generation of Eos commercially available fully packaged QCLAs (The Matchbox) can be tuned over a wavelength range of u ...

Thin-film, lightweight, large-area flexible inorganic solar cells have shown promise to meet the militarys remote power needs on the battlefield. However, thin film solar cells normally have inferior conversion efficiencies due to limited absorption of sunlight by the thin active layer. Various approaches have been investigated to improve conversion efficiencies of thin film solar cells. Among the ...

While aluminum casing materials provide some enhanced performance and thermal loading to explosive ordinance, their overall effectiveness is highly limited by incomplete combustion and long residence times. In order to reduce these problems, the casing material must be designed to facilitate rapid fragmentation through either specialized casing geometries or greatly refined initial particle sizes. ...

For effective protection against EMP and HPM threats, it is important to understand the physics of the threats, and also to quantify the effects they have on electrical systems. EMP and HPM vulnerability testing requires delivery of high peak power and electric fields to distant targets. The most practical solution to simulate such environments is to develop a modular, optically-isolated MV-antenn ...

The introduction of substandard or counterfeit materials into the DoD supply chain can have extremely expensive, and potentially life threatening, consequences. Current techniques used to detect nonconforming materiel can be destructive (e.g., manual sectioning and inspection of a part), time consuming and expensive (e.g., micro-computed tomography, ultrasound), or provide only limited informatio ...

A human produces more than 100 Watts of waste heat during normal activity. If a fraction of this heat energy can be harvested it can replace the stored chemical energy in one or more of the batteries typically carried by soldiers in the field. The current generation batteries, such as the BB2590 are bulky and rigid. The PowerFelt material developed by Wake Forest University is ideally suited for h ...

Laboratory investigations have suggested that acoustically or vibrationally inducing motion in buried targets can aid in improving target detectability through a characteristic response related to differential target motion. This gain is realized by adding an additional degree of freedom, modulation due to motion in the GPR return signal, to use as a discriminating feature. The AKELA team is propo ...

Next Dimension Technologies and Caltech will jointly develop a handheld detector to meet the Armys need for a field-based illicit drug identification system. The project will focus on the design and development of a dual-mode chemiresistive sensor array capable of detecting key drugs of interest, including synthetic cannabinoids and opioids. Novel sensing materials, with enhanced chemical sensit ...

Vuronyx Technologies and Prof. Marya Lieberman at the University of Notre Dame will develop paper analytical devices (idPADs) to presumptively identify illicit drugs. All the reagents needed to perform twelve different chemical color tests are stored on the idPAD. The user rubs the powder to be tested across the PAD, then dips the PAD in water to activate the tests. Within five minutes, a color ...
