Abstract

A cable (104) composed of material capable of conducting light, sound, or electricity is inserted by appropriate means into a material to be examined. A portion of said cable (104) having predetermined parameters is fixed internally within the material. The cable (104) is equipped with anchors (103) that restrict movement within the material to be examined. Displacement or deformation of the material to be examined results in displacement and deformation of the sensor cable system. The anchors (103) preferably concentrate stress or deformation at specific points of the cable as the cable deforms. The anchors (103) may also allow movement of the cable (104) such that displacement and deformation of the cable within the material is reduced. Monitoring is conducted by attaching an appropriate test instrument (108) to said cable that utilizes time domain reflectometry techniques appropriate to the material composition and characteristics of the cable which may be optical time domain reflectometry (OTDR), electrical time domain reflectometry (TDR) or sound time domain reflectometry (SONAR). Said principles of examination or monitoring of the cable (104) determine location and magnitude of displacement and deformation of the cable within the material to be examined.
