Abstract
When using a Fiber Bragg Grating (FBG) for strain measurements it is always necessary to compensate the FBG against temperature fluctuations. In this paper it is shown an innovative method for mechanically compensating an FBG in a high voltage measurement application using an FBG-PZT sensor. The system takes advantage of a mechanical assembly that, as the PZT displaces, the screw where the FBG is bonded on displace in the opposite direction, keeping the FBG length constant. A theoretical analysis is done and experimental results are shown.
