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 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

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 ...

This project proposes to investigate the efficiencies of several material systems in which the ability to draw three dimensional images in red, green, and blue using two-step, two-frequency upconversion in a solid-state medium has already been demonstrated. The technology under investigation provides true RGB three-dimensional display capabilities which feature unlimited, unencumbered viewing acce ...

We Propose to enhance rotorcraft simulation model to support land and sea-based flight testing and operational analysis. The model enhancement will resolve the long-time perplexing problems related to the fundamental simulation requirement for an accurate prediction of rotorcraft response in full range of flight. The solution proposed is to improve the widely used finite state dynamic wake ...

The Multiple Degree of Freedom Measurement (MDFM) System, developed under Wright Laboratory, has been identified as having strong commercial potential as a significant enhancement to existing products in the machine tool industry for machine tool calibration or coordinate measuring machine enhancement. The MDFM is in need of revision to incorporate state-of-the-art technology, to prepare the devi ...

A new Navy process substitutes low toxicity trivalent chromium for toxic hexavalent chromium in aluminum conversion coatings. Further work is needed to investigate variations on the original formulations, with special consideration to formulas useful with common alloys of aluminum. Both a yellow and a blue-bright conversion film are desirable. Fractional Factorial Experimental Designs will be used ...

The objective of this research is to design and implement error-correction coding in a free-space laser communication channel to correct both single bit and burst errors at a user data rate of 155 Mb/s. Correcting these errors will significantly increase the reliability and weather-dependent availability of lasercom systems. Standard error-correction codes add redundant data to allow for correcti ...
