摘要
The invention relates to a method for sensing strain in a component in a wind turbine comprising an optical sensor system. The method comprises the step of inputting a optical signal into at least one optical fibre of said sensor system comprising one or more fibre Bragg grating sensors. Further, the method comprises the step of measuring the transmitted optical signals of said one or more sensors with at least one light detector connected to the other end of said at least one optical fibre, and processing the measured signals in a control unit in order to establish a value of the strain for the component. The invention also relates to an optical strain sensing system for a component in a wind turbine and uses hereof.
