ABSTRACT:
A fiber optic detection system comprising an array of fiber optic elements is presented. Each fiber optic element is uniquely encoded using a plurality of discrete ferquencies, digital codes or other encoding techniques. When a break occurs in one or more fiber optic elements, the missing light frequencies or digital codes are sensed, thereby indicating the break. Preferably, the fiber optic elements are arranged in a grid pattern so that precise location of the break can be made.
