High-speed polarization fiber sensors optimized for security purposes

Abstract

Contemporary advancements in polarization fiber sensor technology offer the potential for substantial enhancements in the responsiveness of security systems, enabling their deployment even in hazardous environments. A significant advantage of these systems is their sensitivity. These fiber systems are faster and safer compared to other security sensors. The possibility of utilizing fiber sensors in environments with an explosion risk makes them irreplaceable in military facilities. This paper focuses on the analysis, design, and testing of a polarization fiber sensor in military applications. The design is focused on monitoring changes in temperature in order to detect object disturbances. Such a detector would act as a very fast, sensitive, and above all non-electrical security system. Further, the design also focuses on changes in pressure that can accompany occurrences such as the passage of military vehicles or the deflections of bridge and building structures in industrial Ex-proof dangerous areas. The amount of different arrangements and measured waveforms makes our work a unique study that confirms the universality and advantages of optical fiber polarization sensors.
