Compensation of thermal blooming and high scintillation affects requires simultaneous large amplitude and large bandwidth operation or high gain bandwidth. Present deformable mirror technology, provides 3 to 4 microns stroke with a full amplitude bandwidthapproaching 500-Hz. It has been a design criteria that as the bandwidth increased, the amplitude decreased specific to a power spectral density ...

"Current plans for high-power defense systems such as ABL and SBL, require adaptive mirrors that can handle high-power requirements, correct wavefront errors, and perform precise pointing and tracking. Normally separate devices that increase the complexityof the beam train handle these functions. Two problems must be addressed. First, high-power laser systems degrade the optical quality of thei ...

The development of a truly solid state high power lithium battery is dependent upon the successful identification of a suitable solid polymer electrolyte. Polymer electrolytes hold the promise of allowing use of lithium metal anodes which could boost thetheoretcial energy density of batteries by as much as 35%. Addition of new high voltage cathodes would result in a high energy, high power lithiu ...

"AlGaN-based heterostructures have demonstrated versatility in optical and electronic applications which is practically unmatched by other material systems. The AlGaN/GaN high electron mobility transistors (HEMTs) constitute a leading candidate forsimultaneously realizing ultra-high frequency low noise amplifiers and power amplifiers. The electron transport properties at the AlGaN/GaN interface al ...

OPTICAL COMPUTERS ARE RECOGNIZED AS POTENTIALLY USEFUL ELEMENTS IN THE QUEST TO MEET THE INTENSE BATTLE MANAGEMENT COMPUTATIONAL REQUIREMENTS OF THE SDI PROGRAM. CURRENTLY, OPTICAL COMPUTERS ARE GREATLY LIMITED IN PERFORMANCE BECAUSE NO EXISTING NONLINEAR LIGHT MODULATION DEVICE SIMULTANEOUSLY OFFERS FAST OPTICAL SWITCHING WITH HIGH GAMMA (THRESHOLD), HIGH SPATIAL BANDWIDTH, LOW POWER DISSIPATION, ...

A solid-state, dense, random optical cross-switch is commercializedto fill needs in the commercial metro-core telecom market, and to supplyrapid, multi-channel, covert, and frequency agile optical communications tothe national missile defense initiative. The optical switch is based uponFabry-Perot and Holographically Dispersed Liquid Crystal (H-PDLC) technology.The deliverable is entirely solid s ...

"As computer workstations continue to increase in the ability to display more information, the necessity for an intuitive Command and Control (C2) display becomes paramount. Interaction efficiency is critical to avoid operator fatigue and minimize operatorerror rates that could cost lives. In emerging C2 systems and concepts, the user typically acts as a manager by exception while the majority o ...

"Current host-based intrusion detection systems are mostly based on attack signatures and are unreliable for detecting insider and/or new attacks and they create too many false positives so that administrators become complacent about potential securityrisks. The opportunity exists to build hierarchical statistical models for host-based intrusion detection systems that will perform deviation detect ...

"Improving performance while reducing cost and weight of kinetic energy kill vehicles and components will require the development of several innovative improvements in materials, processing and manufacturing technologies. For example, many accepted rocketnozzle-manufacturing processes are labor intensive, consume excessive amounts of energy and time, and force engineering tradeoffs involving geome ...
