Title: Embedded fiber optic sensor

Abstract: This invention is directed to a optical fiber embedded in a composite material that, prior to installation, is prepared by cleaning, placing end connectors on at least one end and coating with a protective material. The optical fiber is further coated with an X-ray opaque material compatible with the composite material that allows x-rays, during a machining process, to identify the location of optical fiber when embedded in the composite material.
