PHOTOCHROMIC ELECTRICAL AND THERMAL PROPERTIES OF FLUID FILLED TRANSPARENCIES

PROTOTYPES OF MULTILAMINATE TRANSPARENCIES HAVING A CLOSED FLUID COUNTERCURRENT FLOW CIRCULATING SYSTEM WITH A THERMOELECTRIC SYSTEM WILL BE ADAPTED IN SEVERAL WAYS TO ACHIEVE: 1) PROTECTION AGAINST INCIDENT IR. 2) REGULATION OF INNER TRANSPARENCY SURFACE TEMPERATURE. 3) DYNAMIC RESPONSIVENESS TO INTENSE INCADESCENT FLASH. 4) SURFACE PROTECTION AGAINST LASER INDUCED OPACIFICATION OF TRANSPARENCY. 5) POTENTIAL INDUCTION IN EMP PASSAGE. EVALUATION OF PERFORMANCE OF TRANSPARENCIES WILL BE DONE IN BLACK BOX SYSTEMS WITH THERMAL PROBES ON AN OPTICAL BENCH WITH APPROPRIATE SENSORS, AND LASERS. THERMAL REGULATION WILL BE DONE WITH THERMOELECTRIC MODULES MOUNTED ON FLUID SUPPLY LINES USING THERMOCOUPLED FEED BACK. THERMOELECTRIC DEVICES CAN ACHIEVE BOTH RAPID HEATING AND/OR COOLING WITH THE ADVANTAGE OF BEING DONE ELECTRONICALLY. PHOTOCHROMIC MATERIALS WILL BE EVALUATED FOR FLASH PROTECTION USE. THOSE DIFFERENT TYPES OF PHOTODYNAMIC RESPONDERS WILL BE STUDIED FOR UTILIZATION IN THIS SYSTEM: 1) PHOTOCHROMIC RESPONDERS. 2) FARADAY EFFECT DEPENDENT RESPONDERS. 3) CHARGE INJECTION RELATED RESPONDERS. RADIO FREQUENCY SPUTTERING AND MAGNETRON SPUTTERING WILL BE USED TO GENERATE PROTECTIVE AND RESPONSIVE FILMS. FLUID FLOW CHARACTERISTIC WILL BE ESTABLISHED AND THE EFFECTIVENESS OF CIRCULATING FLUIDS AND PHOTOCHROMES WILL BE COMPARED WITH MATRIX FIXED SURFACE FILMS.
