ABSTRACT:
An apparatus and method for utilizing the deformation characteristics of optical fiber transmission paths to enable the detection of deformations in materials, in which the fibers are disposed in relation to the material such that each separate deformation in the material lying in the path of the fiber results in a corresponding independently measurable deformation along the length of the fiber.
