Abstract

In this work, a random forest regression was used to predict the temperature of an interferometric optical sensor over a wide measurement range, overcoming several times the

$2\pi $

ambiguities. In particular, in the Fabry-Perot interferometer, this phenomenon is related to the free spectral range (FSR) of the fringes. Additionally, spectral features such as wavelength and amplitude of fringe peaks usually present nonlinear relationships with the target physical variable, in this case temperature. Here, it is shown that by using a random forest (RF) regression it is possible to overcome several FSR ambiguities, to widen the measurement range by a factor of 8 from 5.2 to 49.6 °C, with a RMSE of 0.04554 °C and a MAE of 0.0317 °C.

随机森林回归提高温度干涉传感器测量范围

在这项工作中，使用随机森林回归来预测宽测量范围内干涉光学传感器的温度，克服了几倍于$2\pi $的模糊性。特别是在法布里-珀罗干涉仪中，这种现象与条纹的自由光谱范围（FSR）有关。此外，光谱特征，如条纹峰的波长和振幅，通常与目标物理变量呈非线性关系，在这里是温度。本文表明，通过使用随机森林（RF）回归，可以克服几个FSR歧义，将测量范围从5.2°C扩大8倍至49.6°C， RMSE为0.04554°C， MAE为0.0317°C。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
