Wind resistance study of a new steel/quartz nested composite F-P sensor

Due to the limitations of structure and materials of the traditional F-P sensor, it is difficult to complete the measurement work under harsh and complex working conditions such as aero engines, and it is easy to brittle and fail under complex internal and external forces. In order to improve the reliability of the optical fiber F-P sensor under harsh working conditions, this paper proposes a new type of stainless steel/quartz nested composite F-P sensor, which can not only realize strain measurement, but also reduce the influence of the external harsh working environment on the fragile optical fiber and the capillary quartz tube, effectively reduce the impact of air flow on the sensing element in the working environment, and significantly improve the wind load resistance of the F-P sensor.
