Abstract :
There are many noises in the fibre-optic strain sensor system, which directly affects the resolution and stability. For the practicability of the system, the denoising to the output signal must be carried out. In this paper, the original spatial correlation wavelet denoising has been improved and applied to analyze the data of fibre-optic strain sensor signal. The simulation results show that the improved spatial correlation denoising can perfectly remove the noise from the sensor signal.
