Research abstract

THE PHASE I EXPERIMENTAL EFFORT WILL DEMONSTRATE THE FEASIBILITY OF A FIELD WORTHY GROUND MOTION SENSOR TO REPLACE PIEZO-ELECTRIC ACCELEROMETERS FOR CONVENTIONAL EXPLOSIVES AND NUCLEAR TESTING. THE OUTPUT SIGNALS OF PIEZO-ELECTRIC ACCELEROMETERS MUST BE INTEGRATED TWICE TO DETERMINE GROUND MOTIONS. THIS PROCESS REDUCES SYSTEM ACCURACY AND MEASUREMENT BANDWIDTH. ADDITIONALLY, AS PIEZO-ELECTRIC SENSORS ARE ELECTRONIC IN NATURE, THEY ARE SUSCEPTABLE TO THE ADVERSE EFFECTS OF ELECTROMAGNETIC INTERFERENCE (EMI) AND ELECTROMAGNETIC PULSES (EMP). THE PROPOSED SENSOR USES AN INERTIALLY DAMPED PASSIVE REFLECTOR, AND LIGHT DELIVERY AND COLLECTION OPTICS. THE PROPOSED SENSOR OUTPUT SIGNAL IS A DIRECT MEASURE OF THE GROUND MOTION. ADDITIONAL SENSOR PROPERTIES, WHICH INCLUDE INCREASED MEASUREMENT BANDWIDTH CAPABILITY, IMMUNITY TO THE EFFECTS OF EMI AND EMP, AND IMMEDIATE COMPATIBILITY WITH FIBER OPTIC DATA TRANSMISSION LINES ENHANCE THE UTILITY OF THIS SENSOR FOR DNA MEASUREMENT APPLICATIONS.
