Abstract

Among different microfiber applications, optical detecting has been attracting in expanding research enthusiasm because of its conceivable outcomes of acknowledging optical fiber sensor with high sensitivity, quick reaction, high adaptability and low optical power consumption. Here is research progression in optical microfiber sensors with respect to their performance on measuring ethanol concentration. Typical microfiber-based detecting structures, including tapers, sensitivity and linearity on diverse wavelength, are summarized. Sorted by optical microfiber sensors for sensitivity and linearity on identifying ethanol concentration are evaluated. This thesis is about application of optical microfiber sensor for ethanol concentration measurement. Ethanol has been chosen as the parameter is to measure the rate of ethanol in human body. Single-mode fiber has been used in this project is because of its high transmission rate and less dispersion. The optical microfiber is developed using tapering process because of its flexibility in controlling the fiber stretch. After done on completing the optical microfiber sensor, an analysis on various ethanol concentrations has been made. From the result table, 1300nm wavelength has the highest sensitivity compare to other wavelength. This make the optical microfiber sensor with 1300nm wavelength is the most suitable for ethanol concentration measurement.
