NASA HAS LONG USED LIQUID HYDROGEN AS A FUEL AND PLANS TO CONTINUE USING IT IN ASSOCIATION WITH THEIR ADVANCED NUCLEAR THERMAL PROPULSION TECHNOLOGY. HYDROGEN FIRE DETECTION IS CRITICAL FOR ROCKET PROPULSION SAFETY AND MAINTENANCE. A SIGNIFICANT FIRE AT A ROCKET TEST OR LAUNCH FACILITY COULD BE CATASTROPHIC TO INFRASTRUCTURE OR EVEN WORSE, TO HUMAN LIFE. DETECTION MONITORING IS PROBLEMATIC AS HYDROGEN FLAMES CAN BE NEARLY INVISIBLE DURING THE DAY. NONIMAGING, NONVISIBLE FIRE DETECTION TECHNOLOGY HAS LIMITED RANGE AND CAN SUFFER FROM FALSE ALARMS FROM SOURCES OUTSIDE THE REGION OF INTEREST. LOWCOST VISIBLE IMAGERS, COMMONLY USED FOR WIDESCALE ROUTINE SURVEILLANCE, HAVE LIMITED UTILITY DETECTING HYDROGEN FIRES. ALTHOUGH IT HAS BEEN KNOWN FOR DECADES THAT MULTISPECTRAL IMAGING OUTSIDE THE VISIBLE RANGE CAN BE USED TO DETECT FIRES WITH LOW FALSE ALARM RATES, THE PRICE OF SUCH SYSTEMS AND THE LACK OF PROCESSING ALGORITHMS AND THE ABILITY TO IMPLEMENT THEM IN REALTIME HAS LARGELY PROHIBITED THEIR USE. DURING THIS PROJECT WE WILL DEVELOP A LOWCOST IMAGING CAPABILITY THAT FUSES DATA COLLECTED FROM SENSORS OPERATING IN THE (1) SOLAR BLIND ULTRAVIOLET, (2) THERMAL INFRARED AND (3) VISIBLE SPECTRUM, USING ADVANCED SPECTRAL, SPATIAL AND TEMPORAL PROCESSING TECHNIQUES OPTIMIZED TO DETECT AND GENERATE ALERTS ASSOCIATED WITH HYDROGEN FIRES IN REALTIME. THIS MULTISENSOR, MULTIPROCESSING APPROACH WILL ENABLE US TO AUTOMATE FLAME DETECTION WITH EXTREMELY LOW FALSE ALARM RATES. IN ADDITION TO CONTROL ROOM ALERTS, WE WILL MAKE USE OF THE WIRELESS COMMUNICATION CAPABILITIES FOUND WITHIN SMART PHONES AND OTHER MOBILE DEVICES TO BUILD AN APP TO ALERT KEY DECISION MAKERS AND FIRST RESPONDERS OF A FIRE DETECTED IN REALTIME. THIS MULTISENSOR IMAGING RESEARCH COULD ALSO SUPPORT NASA'S IMPORTANT COOL FLAME MICROGRAVITY RESEARCH OCCURRING ON THE INTERNATIONAL SPACE STATION.
