Article Synopsis
- A new demodulation algorithm has been developed for pressure sensing in optical fiber Fabry-Perot systems, focusing on recovering the absolute phase from a chosen monochromatic frequency.
- The algorithm utilizes Fourier transform techniques to determine the relative phase and interference order, allowing for accurate phase recovery through a linear fit of unwrapped phase-frequency data.
- Experimental results demonstrate that this method achieves a pressure measurement precision of 0.15 kPa, significantly outperforming existing phase slope-based algorithms by a factor of 13.
