Abstract
A new approach for the interrogation of a large number of fiber-optic grating sensors is proposed and demonstrated for a small number of sen sors in which signal recovery is achieved by matching a receiving grat ing to its corresponding sensor. This technique is demonstrated for bo th quasi-static and periodic measurands, and the resolution achieved f or a single sensor-receiving grating pair for quasi-static strain is 4 .12 muepsilon.
