Active standoff detection of chemical and biological agents with lasers has proven to be very effective. Specific targets include chemical vapors, chemical aerosols, and biological particles. Most notably, the FAL (Frequency Agile Laser) sensor developed by ECBC (Edgewood Chemical Biological Center) has shown capability to detect all of these targets with a single device. Also, optical technique ...

Recently significant advances have been made in the high fidelity modeling of electromagnetic phenomena in complex geometries in the time-domain. To make high fidelity simulations of scattering and radiation tractable, the computational region must be truncated in a manner allowing outgoing waves to leave with minimal reflection from the boundary. We, HyPerComp in collaboration with Profess ...

On the battlefield, medics must quickly determine injury severity, treat the greatest threats to life, diagnose hemorrhage and establish a triage order. The objective of this research project is to apply our active, long-term learning technology to the task of modeling and prediction of central blood volume parameters from extremely large, and variable physiological datasets. In Phase I, we appl ...

In this STTR program, Structured Materials Industries, Inc. (SMI) will develop process technology to deposit uniform films of piezoelectric PbZrxTi1-xO3, on substrates with complex 3-dimensional topography. Piezoelectric PbZrxTi1-xO3 films are a critical technology for advanced Micro Electro Mechanical System (MEMS), to provide low power actuation in nanoscale devices. Our technical approach is ...

Successful military operations require dominant control of the electromagnetic spectrum in the battlefield. Smokes and obscurants are becoming increasingly important to block the function of enemy optical tracking systems and sensors during day and night operations. Fielded munitions are optimized for either the visible or infrared regions of the electromagnetic spectrum. A single device that b ...

Very compact, robust, and low cost multi wavelengths burst lasers for standoff CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive) detection and identification are proposed. Although a single focused laser pulse on target can do the detection, the probability of hitting the right contaminated spot is low. Therefore, scanning a laser pulse train will cover a larger suspected contamin ...

Survival rates for soldiers injured by IED blasts and similar trauma are enhanced by prompt, high-quality medical care. Among the survivors, however, increasing numbers report symptoms of Traumatic Brain Injury (TBI). Mild and moderate TBIs with no skull-penetrating wounds are difficult to detect and diagnose with commonly used diagnostic systems. Diffusion Tensor Imaging (DTI), a subset of Mag ...

In the past few years, there have been promising demonstrations of new approaches to short-gate (i.e., sub-nanosecond) operation of single-photon avalanche diodes (SPADs) with gating frequencies as high as 2 GHz. However, these demonstrations have had limitations, including operation at just a single fixed frequency, fairly high residual afterpulsing levels, and the lack of industrialization req ...

The proposed project focuses on a new technology that has a built-in switch to turn the filter on and off, and thus is functionally equivalent to a high-selectivity filter and a low-loss switch, where the switch draws no DC power. Agile calls this new invention the Switchable Trimmable Acoustic Resonator (STAR). An array of such filters could implement a very compact and reconfigurable high-sele ...
