Abstract
Simple, rugged intensity type fiberoptic vibration sensors have been developed and pre-production prototypes presently are being evaluated. The transduction element consists of a pair of multimode optical fibers, one mounted on a cantilever reed, the second on a fixed anvil. At frequencies well below the reed's resonant frequency, light coupled from one fiber to the other is directly proportional to the acceleration. The basic operating characteristics of the sensors, detailed laboratory test results and preliminary field data are presented.
