Abstract

Recently the author of this article proposed a new signal processing algorithm for an all fiber white light interferometer. In this article, an all fiber white light interferometric absolute temperature measurement system is presented using the previously proposed signal processing algorithm. Stability and absolute temperature measurement were demonstrated. These two tests demonstrated the feasibility of absolute temperature measurement with an accuracy of 0.015 fringe and 0.0005 fringe, respectively. A hysteresis test from 373K to 873K was also presented. Finally, robustness of the sensor system towards laser diode temperature drift, AFMZI temperature drift and PZT non-linearity was demonstrated.

摘要

最近，本文作者为全光纤白光干涉仪提出了一种新的信号处理算法。在本文中，利用先前提出的信号处理算法，展示了一种全光纤白光干涉绝对温度测量系统。演示了稳定性和绝对温度测量。这两项测试分别证明了绝对温度测量的可行性，精度分别为0.015条纹和0.0005条纹。还给出了从373K到873K的滞后测试。最后，展示了传感器系统对激光二极管温度漂移、AFMZI温度漂移和PZT非线性的鲁棒性。
