ABSTRACT
ABSTRACT: There has been considerable interest recently in the development of fiber optic sensors based on white light interferometry. The use of such a technique for distributed strain or temperature sensing in advanced composite or other structural materials has been discussed in several recent articles. Fiber optic Michelson sensor arrays are of particular interest for such applications because a number of reflective-type sensors networked either in a serial or a parallel topology may be interrogated by use of a common path-length variable reference, thus keeping the system cost down. Several schemes have been reported for multiplexing this type of sensors. These include coherence turning, time-division, Spatial division, duplicate fiber optic switch and 1 × N star coupler multiplexing technique.
