A New Methodology for Fiber Optic Strain Gage Measurements and its Characterization

摘要

A new method for mounting fiber optical strain gages to structures will be proposed which is fast, easy and reliable. Mounting of the sensors happens by means of a specially designed mounting tool called a UV sensor pad. It is used in combination with a UV-curable adhesive. The characterization of the performance of these sensors was investigated in an extended research programme and the deduced results will be presented. It will be shown that these sensors exhibit superior characteristics compared to electrical foil gages and hence this is a very promising new measuring technique.
