THE OBJECTIVE OF THIS PROPOSAL IS THE DEVELOPMENT OF A PULSED MID-IR LASER IN THE 3.5 TO 4.1 MICROMETER ATMOSPHERIC TRANSMISSION WINDOW. SUCH SPECTRAL SOURCE IS RELEVANT TO A VARIETY OF TACTICAL APPLICATIONS. THE DF CHEMICAL LASER HAS BEEN THE CHOICE, BUT SUFFERS FROM WASTE FUEL MANAGEMENT PROBLEMS. NO OTHER EFFICIENT DIRECT LASING SOURCE IS AVAILABLE. TO OBTAIN SUCH A SOURCE, WE PROPOSE THE USE O ...

THE NEED FOR ENERGY CONSERVATION TO REDUCE US DEPENDENCE ON POTENTIALLY UNSTABLE FOREIGN ENERGY SUPPLIES IS WELL DOCUMENTED. ONE MAJOR POTENTIAL ENERGY CONSERVATION MEASURE IS COMBUSTION WITH OXYGEN ENRICHED AIR. CONVENTIONAL METHODS FOR PRODUCING OXYGEN ENRICHED AIR ARE UNECONOMICAL AND HENCE ARE NOT PRACTICED. MEMBRANE PROCESSES, ESPECIALLY THOSE BASED ON IMMOBILIZED LIQUID MEMBRANES ARE CHARATE ...

SURVIVAL IN NEAR-FUTURE BATTLEFIELD SCENARIOS MAY DEPEND UPON THE USE OF HOLOGRAPHIC OPTICAL ELEMENTS (HOES) WHOSE UNIQUE FUNCTIONS SERVE: TO PROTECT PERSONNEL FROM EYE-DAMAGING RADIATION, TO SIMPLIFY AIRCRAFT PILOT VISUAL FUNCTION, AND TO PROVIDE VASTLY IMPROVED COMMUNITIONS AND SIGNAL PROCESSING SYSTEMS. THESE AND MANY OTHER COMPELLING CAPABILITIES OF HOES CAN ONLY BE EXPLOITED IF THEY CAN BE PR ...

THE OXYGEN MOLECULE HAS A NUMBER OF WEAK ABSORPTION LINES INTHE 7000 A SPECTRAL REGION. BY COOLING, THE R1 LINE OF RUBY(A12O3 : CR+3) CAN BE SHIFTED TO COINCIDE WITH 50% ABSORPTION AT LINE CENTER IN THE SOLAR SPECTRUM. RUBY FLUORESCES WITH HIGH QUANTUM EFFICIENCY, WITH A TIME CONSTANT OF APPROXIMATELY 4 MS AT THE TEMPERATURES OF INTEREST. BY DETECTING THE RERADIATED LIGHT, THE RUBY CRYSTAL IS USED ...

THE PROPOSED RESEARCH WILL INVESTIGATE THE DEPOSITION OF AMORPHOUS CARBON THIN FILMS USING A NOVEL LASER ASSISTED DEPOSITION TECHNIQUE. IN THE PHASE I RESEARCH, AERODGNE RESEARCH, INC. WILL DETERMINE THE ABILITY OF THE DEPOSITION TECHNIQUE TO CONTROL THE CARBON BONDING IN THE THIN FILM. IN THE PHASE II STUDIES THEY WILL INVESTIGATE THE RELATIONSHIP BETWEEN DEPOSITION PARAMETERS AND CARBON BONDING ...

FUTURE THREAT INFRARED MISSILE SEEKERS WILL POSSESS THE CAPABILITY TO EFFECTIVELY DISCRIMINATE AGAINST IR DECOY FLARES. NEW DECOY FUELS MUST BE IDENTIFIED WHICH PROVIDE A GOOD SPECTRAL MATCH BETWEEN DECOYS AND HELICOPTERS, AND WHICH HAVE IMPROVED TOTAL RADIANT INTENSITY AND BURNING CHARACTERISTICS. IN ADDITION, ALTERNATIVE DECOY CONCEPTS TO THE FREE-GRAIN FLARE MUST BE EVALUATED. IN THIS PROPOSAL, ...

THE ADVENT OF FIBER REINFORCED COMPOSITES HAS MADE AVAILABLE NEW STRUCTURAL MATERIALS FOR USE IN MILITARY HARDWARE. IN PARTICULAR, ARMOR PANELS MADE FROM FIBERGLASS REINFORCED PLASTICS PROVIDE STRENGTH TO WEIGHT RATIOS SIGNIFICANTLY SUPERIOR TO THOSE MADE FROM METAL PLATE. THESE NEW MATERIALS ARE CRITICAL FOR MAXIMIZING THE PERFORMANCE OF MODER MILITARY ARTICLES SUCH AS HIGH SPEED TANKS AND TROOP ...

THE USEFUL OPERATING LIFE OF MOST MECHANICAL SYSTEMS QUITE OFTEN IS DETERMINED BY THE CONTINUED EFFECTIVENESS OF A VARIETY OF TRIBO-ELEMENTS. THESE TRIBO-ELEMENTS ARE THE DEVICES AND MECHANISMS THAT PROVIDE FOR PROPER LUBRICATION AND FRICTIONAL CONTACT BETWEEN MOVING PARTS. SYSTEMS WHICH CAN MONITOR TRIBO-ELEMENT WEAR CAN PERFORM TWO VERY USEFUL FUNCTIONS: 1) THEY CAN MINIMIZE DOWN TIME BY ENSURIN ...

LEAD IODIDE (PBI2) IS A LITTLE USED COMPOUND SEMICONDUCTOR. THE HIGH ATOMIC NUMBERS OF ITS CONSTITUENT ELEMENTS GIVES ITEXTRAORDINARY PHOTOELECTRIC ABSORPTION EFFICIENCY FOR GAMMA PHOTONS, WHILE ITS 2.5 EV BANDGAP PROMISES PERFORMANCEAT TEMPERATURES UP TO 250 DEGREES C. IT HAS SHOWN SOME PROMISE AS A HIGH EFFICIENCY SOLID-STATE DETECTOR, BUT EARLYDEVICES WERE LIMITED BY MATERIAL IMPURITIES AND IMP ...
