A novel technique of using a 1 x N star fiber optic coupler as a distr
ibuted strain sensor in a white-light interferometer to measure the di
stribution of strain is presented. The measuring principle and 1 x 4 s
tar coupler with four fiber optic strain sensors are demonstrated. The
experiment is performed with four sensors attached to a combination p
lastic specimen. (C) 1998 Optical Society of America.
