Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses a ...

Alameda Applied Sciences Corporation (AASC) proposes to develop an all-solid-state, compact, portable, multi-gigawatt poer modulator for electron and ion beam diodes, high power microwave and x-ray sources. This modulator is based on Inductive Energy Store (IES) using an array of Diamond Opening Switches for power compression. Because power amplification using IES requires a much smaller volume ...

Alameda Applied Sciences Corporation (AASC) proposes a two phase effort with the ultimate goal of producing a marketable high power, high repetition rate diamond switch suitable for use in several defense and commercial applications. In Phase I a set of experiments will be carried out that will show operation at kilohertz frequencies with closing and opening times

Alameda Applied Sciences Corporation (AASC) proposes a three phase effort with the ultimate goal of producing a marketable diamond switch suitable for several pulsed power and other applications in the defence arena. The presently used spark gaps have several drawbacks including switch jitter, large and variable inductance, lifetime and physical size. A low inductance solid-state switch capable ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify concealed weapons. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by algo ...

Accuwave Corporation has developed a narrow bandwidth (1/8 angstrom) optical imaging filter operating in the red. A critical need exists for narrow bandwidth imaging filters with a wide field of view. In this proposed research effort, Accuwave filter technology will be extended to a wider field of view using multimple holograms stored in a LiNb03 crystal.

Accuwave Corporation will study the feasibility of a volume holographic, phase-encoded optical image correlator for credit card and document validation and security application. Fourier transform holograms of a phase-encoded input image are stored using wavelength multiplexed holographic gratings in a photorefractive crystal. High spatial resolution images can be sotred with low crosstalk using ...

The single most important type of metal/SiC junction is the n-type, rectifying Schottky diode, because it is the voltage blocking junction in all majority carrier devices. A reliable junction of this type for n-type SiC is the key to its development for high temperature, power conditioning electronics. Phase I will demonstrate that osmium is the ideal metal for forming such junctions. Phase II wil ...

Acroamatics, Inc. proposed to perform research to develop a method permitting the telemetric transmission of avionics bus data from an air vehicle under test to a remote receiving station using a narrower radio frequency (rf) bandwidth than presently required. Increasing use of digital avionics in aircraft and reduced availability of rf spectrum make this an important topic of development. The s ...
