| Abstract:The paper brings forward a sort of pressure sensor that made of stretch film piece and slightly bend concoct construct, it use OTDR distributing optical fiber pressure sensor. It roundly expatiate theory of single slightly bend optical fiber’s pressure sensor and system of measure rock body thrust, analyses and demarcate delicacy and space distinguish. The optical fiber pressure sensor have characteristic of high delicacy and pace distinguish and finer practicability, passed field test. |
