Abstract:
1. A method of manufacturing a wind turbine, the method comprising: providing a group of wind turbine blades, each blade comprising an optical fibre, each optical fibre incorporating a plurality of optical fibre Bragg grating sensors, with each of the sensors within a single fibre having a resonant wavelength in a distinct wavelength band, and at least some of the sensors in different fibres having a resonant wavelength in the same wavelength band; selecting from the group of wind turbine blades a sub-group of wind turbine blades and assembling the sub-group of wind turbine blades together to form a wind turbine; connecting each of the optical fibres of the wind turbine to a data processing device via a multiplexer and an optical output, wherein the data processing device is configured to process signals from fibre Bragg grating sensors and the multiplexer is configured to control the passage of signals from the optical fibres to the data processing device, such that signals from only one optical fibre are received at the data processing device at any given time.
