Brillouin distributed optical fiber sensor is suitable for measuring the static temperature/strain, but Mach-Zenhder interferometer distributed optical fiber sensor (DOFS) can be used to measure the dynamic strain. Many practical applications need static and dynamic sensing information, which is beyond the capability of the single mechanism distributed optical fiber sensor. Considering optical-fiber sensors of Brillouin optical time domain analyzer (BOTDA) and optical-fiber sensors of Mach-Zenhder interferometer are both using the loop sensing fiber structures, BOTDA and Mach-Zenhder interference are combined together by sharing with the same sensing optical fiber, light source, and other optical devices. BOTDA is used to measure temperature, and Mach-Zenhder interferometer is applied to measure vibration. So, the sensor with multi-mechanism and multi-parameter can be achieved. A preliminary 25 km sensing experiment system is built for testing. For Mach-Zenhder′s vibration sensing, spatial accuracy can reach to 60 m, and the vibration frequency is able to be obtained. For BOTDA′s temperature testing, the beginning and end′s measurement accuracy are 2 ℃ without vibration in existence, and the accuracy becomes 3 ℃ and 4 ℃ respectively with vibration.
