Design considerations in making a broad-range fiber optic pH sensor

The general background and theoretical aspects involved in making a broad-range fiber-optic pH sensor will be discussed. A dye-indicator-based pH measurement depends on the equilibrium position between two or more colored forms of a dye--the ratio of the colored forms is a function of pH.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
