ABSTRACT: A system that operates at room temperature and that could scan for concealed weapons from standoff distances of >10 m would be a tremendous asset for US military homeland security personnel worldwide. THz imaging can, potentially, be used for this application, but it requires the development of a new class of THz detectors whereby the signal to noise ratios are improved significantly. ...

In today’s information age, there are vast resources of data on every region of the Earth. The application of geospecific imagery over large areas has been limited to terrain for the most part. The hindrances to full use of geospecific imagery are the labor required to create the databases, and limits on the rendering capacity of current image generators (IGs), both in polygon count and texture ...

The Phase I effort was successful in experimentally showing feasibility of a combined isotope transmitter that can be developed and demonstrated under the Phase II program. The initial experimental results give the window of gas mixtures for a stable discharge. Laser extraction tests were accomplished with C12/C13 mixtures to give guidance for further work to increase laser gain. For application ...

In the Phase I STTR, N08-T029 “Novel Fiber Optic Methods for Sensing Shape, Orientation and/or Heading of Undersea Arrays and Tethers” a concept was developed for a fiber optic sensing array and shape reconstruction algorithm to be used for situation awareness of flexible undersea cable structures. Undersea cable structures are deployed in environments unsuitable for direct in-situ observation ...

Defects of mitochondrial performance limit physical and cognitive endurance, and resistance to age-related deterioration and trauma. However large scale screens to identify drug-like compounds that improve mitochondrial function have not taken place, bec

Currently large capacity cryostats, capable of hosting experiments for many qubits, require expensive and hard to obtain liquid cryogens. A few small cryo-free systems exist but they are non-ideal for this use. An opportunity exists for a large scale, c

This research investigates the feasibility of improving operational readiness, reliability and availability of high current cryogenic rf linear accelerators using a cryogenic compatible resonant coupling technique to couple all of the accelerator sections together, including any room temperature portion. This technique guarantees a single resonant frequency for the system insuring rapid turn on. T ...

Synthetic scenario-based training of Navy personnel in the use of Navy SIGINT/IO systems has helped to reduce training costs, and it has enabled the personnel to be trained in an environment that sufficiently approximates real-world situations that could not otherwise be accomplished within the class room. However, scenario development is highly complex and involves a great deal of human effo ...

Compelling applications of infrared ultrafast lasers—ranging from ship self defense and aircraft self defense, to medical and micromachining applications—have defined a critical performance point at about one millijoule per pulse from a reliable and robust portable laser system with high average power. Increasing amplifier efficiency is a critical need in order to reach high average powers nee ...

In this project we propose to demonstrate the feasibility of an external pipe sensor for measuring sound pressure levels in submarine piping systems. The sensor consists of flexible PVDF wire wrapped a number of integral turns around the pipe exterior. The charge/voltage output of the sensor can be shown to be directly proportional and highly sensitive to the amplitude of the contained fluid pulsa ...
