Abstract

This thesis presents the design and analysis of naringin concentration sensing based side-polished polymer optical fiber. Measuring naringin solution concentration play an important role incommercial and technological applications. For years, polymer optical fibers (POFs) have been very attractive for industrial applications because of their unique characteristics. In this project, I created simple, low cost and efficient set-up for sensing naringin solution concentration using POFs. The purposes for this research are to design a Polymer Optical Fibre (POF) sensor, to design a sensor for single side-polished and multiple side- polished POF, to analyze the performance of the POF sensor by applying naringin concentration sensing and to develop prototype system of the side-polished POF sensor. The varies distance and energy of the source which is non-contact LED (RGB), then single and multiple side-polished optical fiber, also the different concentration of naringin have been chosen as the manipulated variables. All the elements are experimentally analyzed in order to optimize the output voltage. At the end of the project, the performance liquid concentration sensor-based side-polished for naringin concentration detector using Arduino is successfully designed and analyzed. The experimental results show that when the naringin concentration was increased, its response showed a greater loss of optical power due to the light rays in the submerged region of the POF tend to be refracted out of the fiber instead of being totally internally reflected and transmitted when index of refraction of the surrounding liquid medium is increased. This research is useful to be implemented in food industry to ensure the concentration of naringin in the food does not exceed the prescribed value.
