The Holographic Beam Combiner, HBC, proposed here can be used to combine incoherently the output from N lasers into a single aperture. It will have an intensity higher than 90% of the sum of the input intensities, and a brightness that is 0.9N timeshigher than that of the individual input beams. The HBC is based on the storage of multiple holographic gratings in the same spatial location. Using ...

Intelligent Automation Corporation (IAC) has developed under a Phase I SBIR topic a signal processing technique to detect the onset of turbine engine augmentor instabilities known as

The key to producing more confident, real-time, on-wing diagnoses resides in the processing of multisensor data. Adding expensive new sensors is not the solution, but data fusion is. Fusion saves cost and weight; no new sensors are required. Fusionreduces false alarm rates; faults to be seen across multiple sensors. Diagnostic performance is improved by allowing detection of unique fault patte ...

This effort will develop probabilistic micromechanical fatigue life modeling software . The model will integrate material characterization information with turbine engine structural design methods in order to predict the scatter in the fatigue strength ofa component subjected to high cycle fatigue (HCF). Proven feasible in Phase I, the Phase II will extend our analysis from a simple specimen to in ...

The proposed Advanced Cryogenic Loop Heat Pipe (A-CLHP) is an enabling technology for DoD, NASA, and commercial space missions requiring infrared sensor payloads on gimbaled platforms. Using a revolutionary design concept, the A-CLHP can be implementedwith flexible transport sections that allow the sensor to be cooled by a remotely mounted cryogenic mechanical cooler. No other existing passive hea ...

SHAI, in cooperation with our subcontractor, Interface and Control Systems Inc., will develop an operational Mission Planner for Formation-Flying Clusters and demonstrate its potential for use on the TechSat 21 flight experiment. This system will enablepayload scheduling based on detailed orbital and resource constraints for the entire mission. It will maximize the number and quality of observatio ...

As ever more of industry and commerce moves onto electronic networks, there is a growing appreciation for the usefulness of expressive general models of enterprise activities, such as design and manufacturing. Ontologies are commitments to formal declarative multi-purpose representations with clear semantics that can serve as a solid foundation for such models. While there has been much work ...

This proposal addresses the enhanced utilization of space-based Thermal IR (TIR) imagery, a powerful remote sensing method that can operate in nighttime, fog, and haze conditions and can detect subtle thermal signatures. Currently, ambiguities inseparating temperature, emissivity and atmospheric effects complicate the detection and identification of targets against cluttered backgrounds, even usin ...
