介绍了应用距离分辨干涉法（RRI）对实验室和风洞环境下的外源性法布里-珀罗压力传感器进行测量的方法。制作了一个简单，紧凑的传感器头设计，随后使用RRI进行了表征，其灵敏度为1.627 ×10 - 3 rad Pa - 1，噪声标准偏差为9 Pa，数据速率为1.5 kHz。当在风洞测试中安装在高升力机翼上进行表面压力评估时，本文概述的方法能够与传统的商用相对静压测量设备一样出色。
Range resolved interferometry (RRI) applied to the interrogation of an extrinsic Fabry–Perot based pressure sensor in laboratory and wind tunnel environments is presented. A simple, compact sensor head design was fabricated and subsequently characterised using RRI, which was shown to have a sensitivity of 1.627 ×10−3 rad Pa−1 with a noise standard deviation of 9 Pa over a data rate of 1.5 kHz. When installed in a high-lift wing for surface pressure evaluation during wind tunnel testing, the approach outlined here was able to perform as well as a conventionally employed commercial device for relative static pressure measurements.
