Nowadays, optical fiber sensors were widely used in physics and chemistry. And the processing of the optical spectrum signals was important in the sensing area. In the paper, a simple peak and notch search method was proposed to obtain the wavelengths of peaks and notches in the fiber Fabry-Perot interferometer sensor. The method efficiently reduced the noise of the optical spectrum and detected the wavelengths of peaks and notches, and it could be also extended for other optical spectrum signals.
