CONVENTIONAL FILM PROCESSING TECHNIQUES ARE NOT DESIGNED FOR USE IN LOW-GRAVITY ENVIRONMENTS, BECAUSE OF THE DIFFICULTIES ASSOCIATED WITH CONFINING FREE LIQUIDS WHILE PERMITTING THE INTRODUCTION AND TRANSPORT OF ROLL FILMS INTO AND THROUGH THESE LIQUIDS. IN THIS TECHNIQUE, VISCOUS PROCESSING SOLUTIONS ARE EXTRUDED IN THIN LAYERS ONTO THE FILMS EMULSION SURFACE AND RAPIDLY PROCESS THE FILM. ARCHIVA ...

THE PURPOSE OF OUR RESEARCH PROGRAM IS TO DEVELOP A HELIUM-COOLED ABSOLUTE RADIOMETER SUITABLE FOR WIDE-BAND MEASUREMENTS OF THE EARTH'S RADIATION AT AN ANGULAR RESOLUTION TWO ORDERS OF MAGNITUDE BETTER THAN ACHIEVED WITHTHE EXISTING ERBE RADIOMETERS. WE HAVE CONSTRUCTED AND CHARACTERIZED A HELIUM-COOLED RADIOMETER OVER THE PAST FOUR YEARS. THIS SUCCESSFUL INSTRUMENT IS OPTIMIZED FOR LABORATORY ST ...

HETERODYNE HOLOGRAPHIC INTERFEROMETRY AND TIME-AVERAGE HOLOGRAPHY WITH A FREQUENCY SHIFTED BEAM HAVE BEEN PROPOSED FOR USE IN THE MEASUREMENT AND VISUALIZATION OF INTERNAL TRANSONIC FLOWS. A LONG PULSE FLASHLAMP EXCITED DYE LASER HAS BEEN SHOWN TO PRODUCE OVER 50 MILLIJOULES PER PULSE FOR OVER 50 MICROSECONDS TO PRODUCE FRINGES WITH A COHERENCE LENGTH IN THE ORDER OF 30 CM. ALTHOUGH TEMPORAL COHER ...

AN EXPERIMENTAL PROGRAM IS PROPOSED TO EXPLORE THE FEASIBILITY OF USING SOLID FLEXIBLE FILMS FOR THE ELECTRICALMODULATION OF CONDUCTIVE HEAT TRANSFER SO THAT A VARIABLE THERMAL SWITCH MIGHT BE DEVELOPED CAPABLE OF CONTROLLING ENERGY FLOW TO OR FROM AN ADVANCED SPACECRAFT COMPONENT.

THIS PROPOSAL IS TO RESEARCH AND DEVELOP SUPER SENSITIVE ATMOSPHERIC SENSORS USING ELECTROCHEMICAL TECHNOLOGY. THESE SENSORS WILL BE VERY SENSITIVE, SMART, CAPABLE OF SELFCALIBRATING, AND CONTAINS REDUNDANCY FEATURES. THE CONSTRUCTION OF THESE WOULD BE MAKE THEM LESS SENSITIVE TO TEMPERATURE, SHOCK AND WILL HAVE LONG LIFE, WITHOUT COMPROMISING ON THE SELECTIVITY.

THE MAIN OBJECTIVE OF THIS PROPOSED PROGRAM IS TO DEVELOP HIGH PURITY, HIGH TEMPERATURE, SMALL DIAMETER CONTINUOUS SIC FIBERS VIA A CHEMICAL VAPOR DEPOSITION (CVD) PROCESS FOR USE IN CERAMIC AND METAL MATRIX COMPOSITES WHICH WILL BE USED TO FABRICATE COMPONENTS FOR ADVANCED AIR BREATHING PROPULSION AND HIGH TEMPERATURE ENERGY CONVERSION SYSTEMS. IN PHASE I, THE FEASIBILITY OF FABRICATING A HIGH PU ...

HIGH GAIN, LARGE AREA MICROCHANNEL PLATES (MCP) PRESENTLY ARE LIMITED IN BOTH CAPABILITIES AND SIZE BY THE PRESENT MEANS OF MANUFACTURE. THE MAIN PROBLEM IS THAT THE COMPLEXITY OF SHEARING TO CURVE THE INDIVIDUAL CHANNELS INCREASES AS THE SIZE REQUIREMENTS INCREASE. BY A UNIQUE NEW MEANS OF MANUFACTURE, DETECTOR TECHNOLOGY, INC., PROJECTS THAT OPERATIONAL LIMITATIONS WILL BE ELIMINATED. OUR METHOD ...

PHOTOELECTROCHEMICAL ETCHING IS A ONE STEP, MASKLESS PROCESSFOR PRODUCING DIFFRACTION AND TRANSMISSION GRATINGS IN HARD INORGANIC OPTICAL MATERIALS. THE SUBSTRATE MATERIAL MUST BEA SEMICONDUCTOR AND THE ETCHING LIGHT SOURCE MUST BE OF ENERGY GREATER THAN ITS BANDGAP. THE GRATING PATTERN IS PROJECTED ONTO THE SUBSTRATE IMMERSED IN A MILD ETCHING ELECTROLYTE, AND IT IS ETCHED IN RELIEF PREFERENTIALL ...
