Abstract

Fiber optics, commonly referred to as optical fiber, is a medium and system for transmitting information as light pulses over a glass or plastic strand. When light signals are transmitted through fiber optic cable, they bounce off the core and cladding in a sequence of zig-zag bounces, a phenomenon known as total internal reflection. Recently, optical microfiber sensors have received considerable research efforts due to their high sensitivity, detection speed, and ability to use harsh environments. This project aimed to use microfiber optics as a liquid sensor to detect different honey concentrations using a tapering method. The single-mode fiber will be tapered using the tapering method, and the best size of microfiber optics will be used for further investigation as a liquid sensor. Furthermore, the three samples of different concentrations of honey will be tested. Before each test, the fiber would be dipped in the samples and measured. In a line graph, each measurement would have different results. The experiment's findings will be described in terms of sensitivity, correlation, and coefficient of determination of the graph, all of which are completely dependent on the honey concentration and light source.
