Abstract
COMMUNICATION SYSTEMS THAT USE ELECTRO-ACOUSTICAL TRANSDUCERS ARE SUSCEPTIBLE TO DISTORTION OR INTERRUPTION BY ELECTROMAGNETIC INTERFERENCE, ELECTROMAGNETIC PULSES AND RADIO FREQUENCY INTERFERENCE.SHIELDING THE WIRE CARRYING THE ELECTRICAL SIGNAL TO PREVENT INTERFERENCE IS NOT ALWAYS EFFECTIVE OR DESIRABLE. THE OBJECTIVE OF THE WORK PROPOSED HERE IS THE DEVELOPMENT OF A FIBER OPTIC MICROPHONE. THE TRANSDUCER OF THE MICROPHONE WOULD CONVERT ACOUSTIC SIGNALS DIRECTLY TO A MODULATING LIGHT SIGNAL WHICH WOULD BE TRANSMITTED THROUGH A FIBER OPTIC CABLE. THIS SIGNAL WOULD BE IMMUNE TO ANY ELECTROMAGNETIC INTERFERENCE. THIS WORK WILL DESIGN A TRANSDUCER THAT CAN BE PRODUCED BY MICRO-MACHINING OF SILICON. THE DIFFERENT GEOMETRIES POSSIBLE FOR THE TRANSDUCER WILL BE INVESTIGATED AND THE MOST PROMISING SHAPE WILL BE CONSTRUCTED. A MICROPHONE USING THIS TRANSDUCER WILL BE ASSEMBLED AND TESTED.
