There is a growing need to accurately characterize nuclear materials not only for nuclear safeguards and nonproliferation treaty verification but also for forensics and provenance. At present, nuclear material identification requires samples to be collected and sent to laboratories for analysis using large and expensive equipment, such as inductively coupled plasma mass spectrometers (ICP-MS) or s ...

This proposal for Phase II in response to the Defense Threat Reduction Agency (DTRA) topic 212-006 “Algorithm that can locally link radiation detectors (of different resolutions) to enhance identification/ localization capability”. The topic describes the need for an algorithm to support the fusion of multiple and varied detector outputs into actionable information. The specific focus is to id ...

BLUESHIFT, or “Bi-directional Laser Ultrasound Enhanced System using Holographic Imaging For Treatment,” is a handheld non-contact laser ultrasound imaging device for military field triage identification of anomalies in tissue, such as shrapnel and hemorrhages. The size of a cell phone, BLUESHIFT incorporates innovative techniques to measure the skin vibrations from returning ultrasound pulses ...

The ongoing development of new, improved technology for both hardware and software leads to the almost constant upgrade of existing strategic sensor and communications systems and the development and deployment of new systems.  This work addresses warfighter concerns raised in the area of satellite communications and radar, where burst-produced ionospheric disturbances can cause scintillation of ...

To support DTRA’s agent-defeat efforts, we will refine a laser-based Optical Thermocouple (OTC) technology and build and deliver to DTRA a hardened OTC prototype. This OTC system will be capable of quantifying the localized temporal evolution of temperature inside a detonation environment. The OTC technology is based on two-color fluorescence thermometry to determine the temperature. After laser ...

To develop a support tool for detecting retina damage, first a clinical decision support algorithm for rapid analysis of fundus images of the retina before and after laser injury was developed. The retinal images then went through a rigorous image enhancement phase, image data augmentation, and pixel normalization. Following the enhancement and augmentation processes, algorithms were developed to ...

We propose developing new instrumentation based on swept-wavelength external cavity quantum cascade lasers (swept-ECQCLs), to acquire physical/chemical data on chemical weapon agent (CWA) and simulant properties in laboratory-scale explosive testing, and to improve/validate computational fluid dynamics (CFD) codes. In Phase I, we demonstrated laboratory measurements of CWA simulant combustion usin ...

Service members are exposed to high noise environments on a daily basis. Aviation, mechanized, light and armored units are all exposed to environments well in excess of the permissible noise levels. In aviation alone, flight crews spend a majority of thei
