| Abstract: | The optical fiber distributed temperature measurement system is developed for the real time measurement of temperature field in space.In the system,the optical fiber is the transmissive medium as well as the sensitive medium.In this paper,we discuss the theory,design,and composition of the system,and then study the high speed sampling and sample average technique applied in the system.Now this system has been applied in well loging. |
