基于CCPONS编码的单模光纤拉曼测温系统
Single Mode Fiber Raman Temperature Measurement System Based on CCPONS Coding Method
摘要
Abstract
A single mode fiber Raman temperature measurement method based on complementary correlated Prometheus orthonormal se-quence(CCPONS)is proposed to reduce the steady-state temperature measurement error of the sensor.A single pulse with a pulse width of 30 ns,a Golay code with the same pulse width of 64 bits and a CCPONS code with the same conditions are used to carry out comparative experiments.The experimental results show that the steady-state temperature measurement errors of single pulse,Golay code and CCPONS code systems are±6.5℃,±3.8℃and±2.7℃respectively under the condition of 25 km fiber length,demonstrating that CCPONS code provides an effective method for improving the performance of single-mode fiber Raman temperature measurement sensor.关键词
