PRESENT UV FILTERS CAN HAVE VERY HIGH SPECTRAL PERFORMANCE, BUT THE BEST SPECTRAL PERFORMANCE GENERALLY REQUIRES USE OF MATERIALS AND FILTER CONSTRUCTION WHICH ARE NOT WELL QUALIFIED FOR USE IN SPACE AND HAVE MARGINAL IMAGE QUALITY. THE OBJECTIVE OF THIS EFFORT IS TO IMPROVE THIS SITUATION BYREDUCING TO MINIMUM, THE NUMBER OF SUBSTRATES USED AND TOTALLY ELIMINATING CEMENT AND COLOR GLASSES. IN ORD ...

THIS PROJECT ADDRESSES THE PROBLEM OF MEASURING UPPER MID FREQUENCY ERRORS (THOSE WITH PERIODS FROM 0.5 TO 5 MM) ON GRAZING INCIDENCE OPTICS. THESE ERRORS, EVEN WITH AMPLITUDES OF 5 TO 50 ANGSTROMS RMS, HAVE A SERIOUS IMPACT ON SCATTER IN GRAZING INCIDENCE EXTREME ULTRA VIOLET (EUV) AND X-RAY SYSTEMS. CURRENT MEASUREMENT TECHNIQUES ARE LIMITED IN THEIR SPATIAL FREQUENCY BANDPASS, THEIR ABILITY TO ...

THE PROBLEM IS THE FABRICATION OF LARGE ASPHERIC OR GRAZING INCIDENCE MIRRORS. THE PROPOSED INNOVATION IS A GROUP OF EIGHT INNOVATIVE HARDWARE CONCEPTS AND MATHEMATICALALGORITHMS, COMBINED TO FORM A NON-CONTACTING, SELF-REFERENCING, NON-INTERFEROMETRIC METROLOGY INSTRUMENT CAPABLE OF MEASURING FIGURE ERRORS ON LARGE ASPHERIC MIRRORSTO AN ACCURACY OF A VERY SMALL FRACTION OF A WAVELENGTH OF LIGHT. ...

THE PURPOSE OF OUR RESEARCH PROGRAM IS TO DEVELOP AN AUTOMATED FACILITY FOR CALIBRATION AND TESTING OF ELECTRO-OPTIC DETECTORS. WE HAVE DEVELOPED A VERY PRECISE AND FLEXIBLE ELECTRO-OPTIC SERVO SYSTEM WHICH PROVIDES EXTREMELY STABLE AND EASILY COMPUTER-CONTROLLED LIGHT OUTPUT FROM A WIDE RANGE OF LASERS SUITABLE FOR CALIBRATIONSIN THE VISIBLE AND NEAR INFRARED. THE MAIN AIM OF THIS PHASE I RESEARC ...

THE MAJOR DEFICIENCIES IN CURRENT REAL-TIME AUTOMATIC FAULT DIAGNOSIS APPLICATIONS FOR AEROSPACE SYSTEMS ARE THE HIGH RATE OF FALSE ALARMS, AND THE MAINTENANCE PROBLEMS CAUSED BYINTERMITTENT FAILURES. THESE DEFICIENCIES ARE DUE TO THE INACCURACY OF THE UNDERLYING NUMERICAL MODEL ON WHICH THE FAULT DIAGNOSIS ALGORITHM DESIGN IS BASED. THE AIM OF THIS STUDY IS TO DEMONSTRATE THE USE OF EXPERT SYSTEM ...

THE PHASE I EFFORT WILL EVALUATE FEASIBILITY OF DEVELOPING AN ELECTROENCEPHALOGRAPH (EEG) BASED REAL-TIME METRIC FOR USE IN FLIGHT DECK WORKLOAD ASSESSMENT AND FUTURE SELF-ADAPTIVE AUTOMATED COCKPITS. THE APPROACH WILL CENTER ON THE USE OF THE STEADY-STATE VISUAL EVOKED RESPONSE (SSVER), AND INVOLVE ACTIVE PROBING UNDER A RANGE OF PERCEPTUAL AND COGNITIVE LOADING CONDITIONS. ON-LINE SSVER MEASUREM ...

A PROTOTYPE OF A REVOLUTIONARY NEW INSTRUMENT DESIGN HAS BEEN DEVELOPED AS A MANUFACTURING MEANS FOR BOTH LARGE AND SMALL FORMAT, HIGH GAIN MICROCHANNEL PLATES (MCP'S). THE METHOD USED FOR MANUFACTURE HAS BEEN CALLED THE SHEAR METHOD. CONSIDERABLE RESEARCH NEEDS TO BE PERFORMED TO ADDRESS THE MANY PARAMETERS WHICH GOVERN THE SUCCESSFUL APPLICATION OF THIS INSTRUMENT TO THE TASK OF FABRICATING A "S ...

THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO DEMONSTRATE THE TECHNICAL FEASIBILITY OF INCREASING THE THERMAL TOLERANCE AND METAL WETTABILITY OF CARBON COMPOSITE MATERIALS THROUGH THE APPLICATION OF A TITANIUM CARBIDE CERAMIC TO THEIR SURFACE. THE APPLICATION PROCESS WILL BE LASER-BASED AND WILL RESULT IN THE COVALENT BONDING OF THE CERAMIC TO THE CARBON SUBSTRATE SURFACE. THE CERAMIC-LAYERED CARBON ...

A SPACE SUIT VISOR WITH A CONTINUOUSLY VARIABLE GRAY SCALE TRANSMITTANCE IS PROPOSED. THE SOLID STATE LIGHT MODULATORSWILL HAVE A SANDWICH STRUCTURE COMPRISED OF ELECTROCHROMIC THIN FILMS SEPARATED BY A POLYMERIC ELECTROLYTE. THE STRUCTURE IS ANALOGOUS TO A RECHARGEABLE, THIN FILM BATTERY WITH OPTICALLY TRANSPARENT ELECTRODES AND A VISIBLE STATE OFCHARGE. BECAUSE THE DEVICE HAS A LOW POWER CONSUMP ...

A PROGRAM TO DEVELOP A HIGH-TC COMPOSITE WITH THE SUPERCONDUCTING PERFORMANCE AND MECHANICAL PROPERTIES NECESSARY FOR PRACTICAL SPACEBORNE APPLICATIONS IS PROPOSED. A MODIFIED SOL-GEL TECHNIQUE WILL BE DEVELOPED FOR FABRICATING CONTINUOUS FILAMENT HIGH-TC AND HIGH-JC COMPOSITES STABILIZED WITH AN ALUMINUM MATRIX. IN ORDER TO ACHIEVE USEFUL CURRENT DENSITIES, THE MICROSTRUCTURE OF THE SUPERCONDUCTI ...
