Abstract

A fiber-optic amplitude sensor based on the effect of microbending-caused upsetting of total internal reflection intended for temperature monitoring is offered. The measuring breadboard is described for investigating the sensor characteristics. It is shown that several sensors of this type can be integrated in fiber-optic measuring lines to be used in distributed fiberoptic measuring networks. The characteristics of a fiber-optic measuring line composed of three fiber-optic microbending amplitude sensors are investigated. The fiber-optical measuring network on base fiber-optic microbending amplitude sensors with three-direction stacking of lines and dimension 4×4 is suggested. The fiber-optical measuring system for reconstruct the characteristics of distributed physical fields on developed fiberoptical measuring network is described. The results of reconstruction of two temperature influences with 46 and 74,5 Celsius degree value is represented.
