在本文中，我们讨论了光纤传感器，其工作原理和一种评估分布式传感器的测量性能，例如基于布里鲁因散射的光纤传感器（FOSS）和其他用于监测应变的传感器测量是对不同混凝土结构的性能和状况评估的主要关注点。分析使用10cm空间分辨率的可能性。以及PPP-BOTDA测量系统以实现理论研究。
In this paper, we discuss about fiber optical sensors, its working principle and a standard test method of evaluating the measurement performance of distributed sensors such as Brillouin scattering based fiber optic sensors (FOSs) and other sensors for monitoring strain is proposed. Strain and temperature measurements are main concern for the performance and condition assessment of different concrete structures. PPP-BOTDA (Pulse-PrePump Brillouin Optical Time Domain Analysis) and the possibility of access with 10cm spatial resolution was illustrated. The system has been applied in various fields using this 10cm spatial resolution and ±25 με strain measuring precision. This paper reports the result of the theoretical study for the optimal spatial resolution, and the PPP-BOTDA measuring system to realize the theoretical study.
