Research of Detection Method Based on Bending Loss of Optical Fiber for Mineral Emulsion Concentration
摘要
Abstract
Emulsion concentration has a significant impact on working performance and service life of hydraulic support,and we analyze existing detection methods of emulsion concentration.According to theoretical analysis of the relationship between bare fiber bending loss and refractive index,experiments are conducted to study the relationship between bare fiber bending loss and concentration of emulsion,and we put forward a method to determine the concentration of emulsion by detecting bare optical fiber bending loss.A device for detecting bending loss of bare fiber in emulsion is designed,and the relationship between bending loss of bare fiber and different concentrations of emulsion is studied experimentally.The experimental results show that the refractive index of emulsion can be measured by bare fiber bending loss method,and then the emulsion concentration can be calculated indirectly according to the corresponding relationship between the refractive index of emulsion and its concentration.Finally,an on-line measurement method of emulsion concentration based on the principle of fiber bending loss refraction is studied.关键词
