Fiber Optic Sensor for Precise Concentration Measurement

A quasidistributed fiber sensor for solute concentration measurement based on Fresnel reflection from fiber tips and the interrogation of an arrayed waveguide grating is presented. Thin-film filters are utilized to achieve the possibility of wavelength-division-multiplexing. The device consists of two photonic crystal (PhC) fiber-tip sensors: one measures the ethanol concentration via refractive index (RI) changes and the other one is isolated from the liquid for the independent measurement of temperature. Additionally, FOSs have a small size, are lightweight, and. A new and simple calibration technique that greatly enhances the measurement sensitivity of conventional fiber-optic reflectometry based on Fresnel reflection from the tip of a fiber is used for demonstrating the feasibility of measuring solute concentrations and index changes in fluids to very. An inline, real-time optical fiber-based chemical concentration monitor that enables measurements of chemicals used in semiconductor manufacturing processes such as cleaning and etching. Inline real-time measurements can be obtained. 24 September 2007; 91 (13): 131101.
