Title

Temperature Sensing Using Fiber Optics

Authors

Abstract

An optical fiber is a fiber made up of drawing glass (silica) or plastic to a diameter slightly thicker than that of human hair and is flexible and transparent. These types of fibers are used most often as a means to transmit light. This paper designed a multi-channel fiber-optic temperature sensor system (FTSS) using an optical reflectometer (OTDR) for the time domain. The FTSS built consists of fiber-optic temperature-sensing probes, a fiber-optic coupler, an optical fiber transmitter and an OTDR. The fiber-optic temperature sensing probes are composed of silicon oil, a nickel-plated brass seal, a fiber channel (FC) terminator, and an optical fiber single mode. The developed FTSS has four channels connected using single-mode optical fibers of different lengths which have fiber-optic temperature sensing probes. Silicon oil is used as a tool for temperature sensing, because its refractive index varies with the variations in temperature. The paper measured the optical powers of the reflected light signals (Fresnel reflection), which are produced in the distal ends of the sensing probes at the interface between the silicon oil and the center of the single-mode optical fiber. The optical powers of the four FTSS channels were calculated to assess individual temperatures at four different points simultaneously using an OTDR.
