一种基于强度补偿的自由式光纤束差压传感器
A Kind of Freestyle Optical Fiber Bundle Differential Pressure Sensor Based on Intensity Compensation
摘要
Abstract
A kind of freestyle optical fiber bundle differential pressure sensor based on intensity compensation was designed and researched.Firstly,the sensor probe part was designed with double probe and the same structure,and was packaged by mechanical style.Then,the sensor fiber part was designed and analyzed on the intensity compensation,after the compensation,the output value of R was analyzed theoretically with the modulation function M.Finally,R was tested out under different conditions,changing the output power of the light source when there is same pressure p =20 kPa in two probes,or inputting different pressures in two probes.Experimental results show that:through strength after compensation,the output value R≈1,at the same time under the influence of different pressure differentials,the output value R and pressure difference △p within a certain area is of a good linear relationship.Through the above research it is proved that the effects of intensity compensation are obvious and can detect pressure difference.关键词
