A shape capture system for field and industrial capture of surface contours and discontinuous shapes is proposed. The system will provide accuracy of 0.01 inch or better at over 1 million points distributed over a region 100 inches across from three ormore images obtained with a high resolution handheld digital camera. A tripod or bench mounted projector projects a pattern onto the surface from w ...

Future IRCM laser transmitters are being developed based on optically pumped GaSb mid-infrared semiconductor laser, however, the current technology requires the laser to be operated at cryogenic temperature. Aculight and MIT Lincoln Laboratory propose toinvestigate methods to increase the operating temperature of these semiconductor lasers, which will dramatically decrease the cost of the laser t ...

We propose a Yb:SFAP laser system, using a novel resonator scheme, that will provide over 1 J per pulse output at 100 Hz at high efficiency, in a package far more compact, lower mass and efficient that conventional systems. The high-pulse-energy poweroscillator architecture is especially suited to space platforms where weight, volume, cooling and efficiency are particularly important. The propos ...

Advanced IRCM lasers and systems, currently in development, require mid-infrared semiconductor lasers with very non-standard design parameters. The proposed effort will investigate the performance of commercially grown GaSb based materials and optimizetheir performance for use in unique laser transmitter designs, which will be directly traceable to future IRCM systems. The proposed mid-infrare ...

SOCOM, other military branches, and civilian authorities (homeland defense) need ways to rapidly determine the presence of chemical and biological threats and classify their nature. Standoff detection of the threats would greatly enhance personnel safetyand allow more operational flexibility.We propose a novel laser-based system allowing remote measurements of the infrared spectra of aerosols, va ...

The new 10-ppb drinking water standard for arsenic is expected to impact 10% of the nation's community drinking water systems. Large water systems can remove arsenic through their chemical coagulation processes; however, compliance is a much greaterchallenge for systems supplying fewer than 10,000 users, so called

Publish-subscribe-query systems have been evolving from costly, monolithic, proprietary applications into a client-server model based on web services. More recently, distributed peer-to-peer systems based on undifferentiated end-user systems have beenexplored. All of these approaches tend to suffer from inherent architectural scalability limits.Based on its experience in building business-to-bus ...

Advanced Acoustic Concepts, Inc. (AAC) proposes to implement a computational model of human auditory processing based upon cortical theory and to demonstrate its utility to evaluate and improve systems for speech communication and automated recognition ofspectro-temporal patterns. Specifically, AAC believes that unusual brain representations and processing strategies are largely responsible for th ...

Composites that are reinforced with well-dispersed carbon nanotubes have been shown to improve the performance of polymers in many areas such as stiffness, heat distortion temperature, control of thermal coefficient of expansion, and corrosion resistancein extreme environments. However, much of the nanocomposite related research and development has not been directly relevant to carbon fiber reinfo ...

Crested multi-layer tunnel barriers have been proposed, which offer a revolutionary solution to overcome density to speed trade-offs characteristic of present data storage technologies. Practical implementation of the proposed technology will involve useof thin film materials that are readily manufacturable and CMOS-compatible. A critical need exists for experimental verification of the theoreti ...
