Abstract
CURRENT GAS MEASUREMENT TECHNIQUES ARE INADEQUATE TO DETECT GASES USED IN CHEMICAL WARFARE WITH ENOUGH ACCURACY AND RELIABILITY IN THE HOSTILE WAR ZONE ENVIRONMENTS. IT IS NECESARY TO HAVE A SENSOR THAT WILL PROVIDE INSTANTANEOUS AND CONTINUOUS MEASUREMENT OF THE POISONOUS GASES. IT MUST OPERATE IN A HOSTILE ENVIRONMENT, INCLUDING THOSE OF HIGH SMOKE, DUST, AND OTHER VAPER/PARTICULATE CONTAMINATION. THE PROPOSED APPROACH UTILIZES DR. BUCHMAN'S NEW FUNDAMENTAL CIRCUIT IMPROVEMENT TO FIBER OPTIC INTERFEROMETRIC TECHNOLOGY THAT GIVES DRAMATICALLY IMPROVED SIGNAL TO NOISE AND SENSITIVITY (BETTER THAN 10 TO 1 IMPROVEMENT). THIS TECHNOLOGY WAS DEVELOPED AT THE UNIVERISTY OF TEXAS AND ENHANCED BY RESEARCH APPLICATIONS FOR ACOUSTIC SENSORS. UNDER THIS PROPOSAL THE FUNDAMENTAL INTERFEROMETIC TECHNOLOGY IS BEING ENHANCED AND ADAPTED TO A GENERALIZED PHOTO-ACOUSTIC SENSOR. THE SENSOR IS BEING BUILT AS A GENERALIZED GAS SPECIE MEASUREMENT; HOWEVER, ONE GAS WILL BE SELECTED TO RUN COMPLETE PERFORMANCE TESTS. THE PHASE I MILESTONES ARE: - THEORETICAL STUDY OF SENSITIVITY/RESPONSE TRADEOFFS - OPTIMIZATION OF SIGNAL PROCESSING FOR SPECIFIC INTERFEROMETER - BUILD TEST PHOTO-ACOUSTIC OPTRODE - BUILD ENHANCED BUCKMAN INTERFEROMETER - INTEGRATE OPTRODE WITH INTERFEROMETER - TEST FOR PERFORMANCE WITH SAMPLE GAS
