Abstract

A Sagnac distributed sensor based on placement of one or more fiber gratings in the Sagnac loop may be used to measure local strain, integrated strain and the position and location of time varying events. This sensor is described as well as its application to aircraft and spacecraft. Examples are also given of how fiber optic gratings can be applied to a variety of strain sensing situations that are applicable to aerospace.
