However, existing demodulation methods commonly rely on spectrometers, which limits their application to high-frequency pressure signal acquisition. To solve this problem, this study developed a self-compensated, three-wavelength demodulation system composite with an F-P pressure sensor and a thermocouple to construct a comprehensive sensing system. The system produces accurate pressure measurements in high-temperature, high-pressure, and high-dynamic environments. In static testing at room temperature, the sensing system shows excellent linearity, and the pressure sensitivity is 158.48 nm\/MPa. In high-temperature testing, the sensing system maintains high linearity in the range of 100 \u00b0C to 700 \u00b0C, with a maximum pressure-indication error of about 0.13 MPa (0~5 MPa). In dynamic testing, the sensor exhibits good response characteristics at 1000 Hz and 5000 Hz sinusoidal pressure frequencies, with a signal-to-noise ratio (SNR) greater than 37 dB and 45 dB, respectively. These results indicate that the sensing system proposed in this study has significant competitive advantages in the field of high-temperature, high-speed, and high-precision pressure measurements and provides an important experimental basis and theoretical support for technological progress in related fields.<\/jats:p>","DOI":"10.3390\/s24165313","type":"journal-article","created":{"date-parts":[[2024,8,16]],"date-time":"2024-08-16T09:15:41Z","timestamp":1723799741000},"page":"5313","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Performance Study of F-P Pressure Sensor Based on Three-Wavelength Demodulation: High-Temperature, High-Pressure, and High-Dynamic Measurements"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4858-1479","authenticated-orcid":false,"given":"Maocheng","family":"Guo","sequence":"first","affiliation":[{"name":"School of Aerospace Engineering, Xiamen University, Xiamen 361102, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-8573-176X","authenticated-orcid":false,"given":"Qi","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Xiamen University, Xiamen 361102, China"}]},{"given":"Hongtian","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Xiamen University, Xiamen 361102, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9384-6492","authenticated-orcid":false,"given":"Rui","family":"Liang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Dynamic Measurement Technology, North University of China, Taiyuan 030051, China"}]},{"given":"Yongqiu","family":"Zheng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Dynamic Measurement Technology, North University of China, Taiyuan 030051, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5265-0263","authenticated-orcid":false,"given":"Xiang","family":"Zhu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Dynamic Measurement Technology, North University of China, Taiyuan 030051, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3956-3897","authenticated-orcid":false,"given":"Enbo","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Xiamen University, Xiamen 361102, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3757-597X","authenticated-orcid":false,"given":"Zhaoyi","family":"Li","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Xiamen University, Xiamen 361102, China"}]},{"given":"Chenyang","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Xiamen University, Xiamen 361102, China"},{"name":"State Key Laboratory of Dynamic Measurement Technology, North University of China, Taiyuan 030051, China"}]},{"given":"Zhenyin","family":"Hai","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Xiamen University, Xiamen 361102, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26910","DOI":"10.1109\/JSEN.2023.3323318","article-title":"Materials and Sensing Mechanisms for High-Temperature Pressure Sensors: A Review","volume":"23","author":"Chen","year":"2023","journal-title":"IEEE Sens.
