In this proposal, we describe a novel approach for realizing a parallel, nonmechical, read/write interconnection for angle-multiplexed three-dimensional (3-D) optical memories. Our concept represents a significant first step required toward taking this critical memory technology from the laboratory and inserting it into operational systems. The concept utilizes novel optomechanical packaging and ...

RD Instruments has several acoustic sensor technologies which are on the threshold of achieving the affordability, low-power, robustness, and miniaturization needed for autonomous underwater vehicle (AUV) applications. We manufacture Acoustic Doppler Current Profilers (ADCPs), Doppler Velcoity Logs (DVLs), and Correlation Velocity Logs (CVLs). We are also developing a phased array sonar in which ...

The contractor proposes a new approach to underwater imaging that directly converts a two-dimmensional acoustic pressure wave into an electronic requirements fo convential piezo-element arrays. The imager relies on the piezo-birefringent properties of a nematic liquid crystal panel that serves as both sensor and display. The capability of nematic liquid crystals has been established and publishe ...

The High Level Architecture (HLA) for Modeling and Simulation is evolving into the DoD standard paradigm for developing distribution simulation environments through the integration of disparate simulations ("federates"). HLA also has significant potential to provide similar benefits to the commercial software industry in general, and the online distributed entertainment industry in particular. H ...

Significant similarities exist between DoD simulation applications and networked simulation games developed for entertainment. To date, however, there has been no compelling reason for commercial game developers to adopt DoD methods and standards. Interestingly, HLA compares favorably to current commercial solutions like Microsoft's DirectPlay. There is clear benefit to DoD if HLA is embraced b ...

Intelligent Fiber Optics Systems (IFOS) proposes development and implementation of novel power-efficient architectures for photonic networks supporting microdevices such as sensors and actuators based on Micro-Electro-Mechanical Systems (MEMS) and Micro-Opto-Mechanical-Systems (MOMS).Identification of Problem/Opportunity: Wavelength Division Multiplexing (WDM) is increasingly used for high-capaci ...

Viewing the horizon is helpful in reducing the symptoms of motion sickness in ship board personnel. Many of a ship's complement are required to constantly monitor visual displays that are fixed to the deck and provide no view of the horizon. Virtual i-O! proposes a research study where horizon information is provided in combination with a visual display mounted on the head. This information ...

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 ...
