Abstract
Sensor technology plays an important role in the field of measurement science and engineering. Fabry-Perot (F-P) sensor has always been the focus of research due to its high precision and sensitivity. Traditional F-P sensor demodulation algorithms have limitations in terms of demodulation time and precision. In order to pursue higher accuracy and achieve faster demodulation, we report a joint demodulation algorithm based on Fibonacci and cross-correlation. The Fibonacci search method is used to quickly search the cavity length corresponding to the maximum cross-correlation number, and the target accuracy is achieved through search iteration. Experimental results show that this algorithm is used for DualCavity Fabry-Perot Interferometer (DFPI) sensor demodulation, with a resolution of 10 pm and a cavity length demodulation time of less than 0.06 s. This study provides new insights for improving the demodulation efficiency and accuracy of F-P sensors.
