抽象的。介绍了一种多点光纤折射仪，它采用一种算法来补偿由光频扫描激光器产生的非线性。这种补偿允许设计多点感测系统。否则，只能进行单点检测。而且，同时应用于所有感测点的非线性补偿允许在执行补偿之后每个感测点的分辨率的改进。给出了所提出的多点折射率传感器的数学模型和实验结果。
Abstract. A multipoint fiber optic refractometer that uses an algorithm to compensate for the nonlinearity generated by an optical frequency sweeping laser is presented. This compensation allows for designing the multipoint sensing system. Otherwise, only single-point sensing is possible. Also, the nonlinearity compensation, applied to all sensing points simultaneously, permits an improvement in the resolution of each sensing point after the compensation is performed. The mathematical model and experimental results of the proposed multipoint refractive index sensor are presented.
