The aim of this work is to point out the current possibilities of using polarized light in sensor technology. Furthermore, the aim is to demonstrate the possibility of using the fiber sensor of thermal field disturbance as a truly feasible biomedical sensor applicable in medicine and especially to analyse different ways of measuring polarization changes. This paper concludes theoretical and experimental study deal with temperature response of birefringent fiber. It is supposed to use it for design of sensor of temperature disturbance. The paper follows up on the previous works, where the response of the birefringent PANDA fiber to thermal exposure in the temperature range from 0 to 48 °C was studied. These experiments analyzed the dynamic sensitivity characteristic of birefringent fiber for the process of thermal source apposition. The present paper brings a detailed comparative analysis of fiber response to the processes of apposition and the removal of thermal source, which are evaluated from the point of view of the system’s response after the ending of the thermal exposure. For practical use in fiber recovery analyses, the phase development rotation senses are described on the observable Poincare sphere.

热暴露结束后双折射熊猫光纤在恢复到环境温度期间的相移响应

这项工作的目的是指出目前在传感器技术中使用偏振光的可能性。此外，目的是证明使用热场干扰光纤传感器作为真正可行的生物医学传感器应用于医学的可能性，特别是分析测量偏振变化的不同方法。本文总结了双折射光纤温度响应的理论和实验研究。应将其用于温度扰动传感器的设计。该论文延续了之前的工作，研究了双折射 PANDA 纤维在 0 至 48 °C 温度范围内对热暴露的响应。这些实验分析了双折射光纤在热源并置过程中的动态灵敏度特性。本文从热暴露结束后系统的响应角度对纤维对热源并置和移除过程的响应进行了详细的对比分析。为了实际用于纤维回收分析，在可观察的庞加莱球体上描述了相位发展旋转感。
