Abstract:

A FIBER OPTIC PRESSURE SENSOR BASED ON THE PHOTOELASTIC EFFECT IS DISCUSSED. DUE TO INTRINSIC IMMUNITY TO ELECTROMAGNETIC INTERFERENCE,THE FIBER OPTIC SENSOR OFFERS THE PROMISE OF FUNDAMENTAL IMPROVEMENT RELIABILITY. A POLARIMETRIC SENSING TECHNIQUE MINIMIZES THE EFFECTS OF RADIATION DAMAGE TO FIBERS. THE SENSOR EXPLOITS THE CHANGES IN INDEX OF REFRACTION PRODUCED BY STRESS IN PHOTOELASTIC MATERIALS. THEOPERATING RANGE OF THE SENSOR HAS BEEN CHOSEN TO COINCIDE WITH ONE OF THE RANGES OF INTEREST FOR UNDERGROUND NUCLEAR TESTS. AN INVESTIGA TION INTO PHOTOELASTIC SENSING ELEMENT DESIGN OPTIONS IS DISCUSSED.
