ABSTRACT:
A pressure detector including a fiber optical cable woven through a ladder-like structure which is then encapsulated and surrounded by a cover. Light transmitted through the fiber optic cable is diminished to a value less than a threshold value upon the occurrence of microbending caused by pressure applied at any location along the length thereof. The rungs of the ladder-like structure are sized and spaced to provide a proper locus about which microbending may be produced. In addition, the rungs may be round in cross-section and/or otherwise shaped to enhance the sensitivity of the system.
