Abstract
First and second tabs are affixed to the surface of a body in close proximity with each other and in partially side by side relation. First and second optical fibers are affixed to the first and second tabs, respectively, and are movable therewith. The optical fibers are positioned transverse to the tabs and in alignment about a mechanical quiescent point in the absence of strain in the body. A source of light produces and directs light through the first and second optical fibers. A light detector detects light transmitted through the first and second optical fibers and determines the intensity thereof, which is proportional to the magnitude of compression and tension strains in the body.
