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 ...

THIS STUDY IS TO DEVELOP INSTRUMENTATION TO MEASURE DRY DEPOSITION RATES OF ATMOSPHERIC TRACE GASES IM- PORTANT IN STUDIES OF ACIDIC DEPOSITION. THE METHOD IS BASED ON THE WELL-ESTABLISHED EDDY CORRELATION TECHNIQUE AND WILL USE A TUNABLE DIODE LASER SOURCE COMBINED WITH AN OPEN-PATH MULTIPASS ABSORPTION CELL FOR TRACE SPECIES DETECTION AT PARTS-PER-BILLION LEVELS. THIS INSTRUMENT WILL HAVE THE FA ...

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 ...

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 OBJECT OF THE PLANNED RESEARCH IS TO DEMONSTRATE THE FEASIBILITY OF PRODUCING A TRUE THREE-DIMENSIONAL (3-D) DISPLAY FOR VIEWING THE IMAGERY PRODUCED BY EMISSION COMPUTED TOMOGRAPHY SYSTEMS IN THE FIELD OF MEDICINE. THE ULTIMATE OBJECTIVE IS TO DISPLAY HARD AND/OR SOFT COPY COMPUTER-GENERATED HOLOGRAMS VERY RAPIDLY. DURING PHASE I OF THE PROGRAM, A HOLOGRAPHIC DISPLAY INSTRUMENT (HDI) WILL BE ...

THIS PROPOSAL COVERS THE DEVELOPMENT OF A MULTISTAGE CRYOCOOLER USING THE MIKULIN PULSE TUBE CYCLE. THE EFFORT IS DIRECTED TOWARD THE DESIGN OF A HIGH RELIABILITY, LONG LIFETIME 20 K UNIT WITH A REFRIGERATION POWER OF 1 WATT.

ADVANCED METHODS FOR THE CONVERSION OF NATURAL GAS TO LIQUID FUELS ARE NEEDED SO THAT NATURAL GAS ENERGY RESOURCES CAN BE BETTER UTILIZED. IN RECENT RESEARCH BREAKTHROUGHS, CERAMIC MONOLITHS HAVE BEEN USED IN PARTIAL OXIDATION TO CATALYZE VERY FAS, HIGH SELECTIVITY SYNTHESIS OF HIGHER HYDROCARBONS FROM METHANE. USE OF METAL MONOLITHS (SOLID METAL PLATES PERFORATED WITH SMALL, UNIFORM HOLES) IS P ...
