Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back An analysis of temperature influence on fiber-optic sensor having light guide with sequential bend Busurin V.I., Zheglov M.A., M’int Z. The article analyzes the temperature influence on fiber-optic fluid level sensor having light guide with sequential bend. It gives a mathematical model for temperature influence taking into account light guide geometry and refractive index, light emitting unit parameters and controlled liquid refractive index.
