FIBER GREATING OR FIBER STRAIN SENSOR HEAD AND STRAIN MEASUREMENT SYSTEM THEREOF

摘要

A fiber grating or fiber strain sensor head used for various strain monitoring system in complex structure engineering comprises a supporter, a fiber or a fiber grating, and is characterised in that said supporter has a bend structure with a cross breaking part and an endwise part, and said fiber grating or fiber is adhered to the outside surface or the inside surface of said endwise part. A strain measurement system comprises said fiber grating or fiber strain sensor head.
