BIOMAGNETIC MEASUREMENTS CAN NOW MAKE UNIQUE AND SIGNIFICANT CONTRIBUTIONS TO THE STUDY OF ACTIVITY IN THE HUMAN BODY. MOST MEASUREMENTS ARE MADE WITH THE SQUID MAGNETOMETER WHICH HAS SEVERAL MAJOR DISADVANTAGES. THE LONG TERM TARGET OF OPPORTUNITY IN THIS PROPOSAL IS THE DEVELOPMENT OF A COMPACT, SENSITIVE, ROOM TEMPERATURE BIOMAGNETIC SENSOR BASED ON A LASER-STIMULATED FIBER OPTIC INTERFEROMETER ...

THE MATERIALS OF AEROSPACE COMPONENTS ARE SUBJECTED TO HIGH TEMPERATURES AND STRONG AERODYNAMIC FORCES DURING PROPULSION. THEREFORE, INNOVATIONS IN NON-INVASIVE SENSOR TECHNOLOGIES ARE REQUIRED FOR THE MEASUREMENT OF STRUCTURAL PHYSICAL PROPERTIES. FIBER OPTIC VIEWING PROBES AND OTHER OPTICAL MEASURING TECHNIQUES, ALTHOUGH PROMISING, FAIL TO COMBINE FLEXIBILITY WITH QUANTITATIVE ANALYSIS OF PHYSIC ...

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO REDUCE THE SIZE, WEIGHT, AND COST OF THE RELAY OPTICS OF THE AIRCRAFT HEAD UP DISPLAY (HUD), BY REPLACING IT WITH TRANSMISSION HOLOGRAPHIC LENSES. HOLOGRAPHIC LENSES ARE VERY LIGHT AND CAN BE MANUFACTURED AT VERY LOW COSTS. APPLICATIONS OF HOLOGRAPHIC LENSES TO HUD WERE LIMITED IN THE PAST, DUE TO WIDE SPECTRAL BAND OF THE HUD - CATHODE RAY TUBE (CRT). HO ...

THIS PROPOSAL ADDRESSES THE NEED TO DEVELOP A MODEL OF THE AVIONICS INDUSTRY DESIGN PROCESS FOR SELECTED GOVERNMENT PERSONNEL TO USE IN SUPPORT OF UNIFIED LIFE CYCLE ENGINEERING (ULCE) INITIATIVES. INFLUENCING THE DESIGN PROCESS TO ACCOUNT FOR ALL SUPPORTABILITY, PRODUCABILITY, PERFORMANCE, AND COST CONSIDERATIONS IS THE MOST HIGHLY LEVERAGED LIFE CYCLE COST OPPORTUNITY IN THE LIFE CYCLE OF A WEAP ...

THIN-WALLED TUBULAR STRUCTURES ARE EXTREMELY USEFUL FOR STRUTS AND JOINTS IN LIGHTWEIGHT TRUSSES FOR SPACE PLATFORMS, FOR ANTENNA SUPPORT SYSTEMS, AND, PERHAPS, EVEN FOR WAVEGUIDES. ON THE BASIS OF MASS-SPECIFIC PROPERTIES, GRAPHITE-FIBER-REINFORCED MAGNESIUM (GR/MG) COMPOSITES HAVE THE GREATEST POTENTIAL TO SATISFY AEROSPACE STRUCTURAL REQUIREMENTS FOR STRENGTH AND DIMENSIONAL STABILITY (STIFFNES ...

THERE ARE MANY MILITARY AND COMMERCIAL APPLICATIONS WHERE VERY HIGH SPEED AND HIGH RESOLUTION SIGNAL PROCESSING, COMPUTING, IMAGE PROCESSING AND VISION SYSTEMS ARE DESIRABLE. CURRENT SYSTEMS ARE SEVERELY LIMITED BY DEVICES THAT REQUIRE RELATIVELY LONG TIMES TO GET INFORMATION INTO AND OUT OF THE SYSTEM. APPLICATIONS SUCH AS SURVEILLANCE, TRACKING, PROCESS MONITORING, QUALITY CONTROL AND MANY OTHER ...

SAR (SYNTHETIC APERTURE RADAR) IS A RADAR IMAGING TECHNIQUE THAT PRODUCES HIGH RESOLUTION MAPS OF THE RADAR CROSS SECTION OF A SCENE BY PROCESSING THE COHERENT PHASE HISTORY OF THE RETURN SIGNAL OVER MULTIPLE PULSES. SAR SYNTHESIZES AN ANTENNA THE LENGTH OF WHICH IS TWICE THE DISTANCE THE SAR PLATFORM FLIES DURING ONE COHERENT DWELL; SINCE THE AZIMUTH RESOLUTION IS INVERSELY PROPORTIONAL TO ANTENN ...
