光纤压力传感器允许在恶劣环境中进行坚固的高温和超小型压力监测。然而，简单的基于光功率的读出遭受弯曲损耗和光源波动。本文提出了一种基于白色光干涉的差分技术来缓解这个问题。对制作在多模和单模光纤尖端的绝对法布里-珀罗压力传感器进行了白色光谱测量。弯曲损耗灵敏度被证明是减少了79%的因素，通过使用建议的差分光谱技术。
Fiber-optic pressure sensors allow rugged high-temperature and ultra-miniature pressure monitoring in harsh environments. However, simple light power based readout suffers from bending losses and light source fluctuations. This paper presents a differential technique based on white light interferometry to alleviate this problem. White light spectroscopic measurements have been performed on absolute Fabry-Pérot pressure sensors fabricated at the tip of multi-mode and single mode optical fibers. Bending loss sensitivity is demonstrated to be reduced with a factor of 79% by using the proposed differential spectroscopic technique.
