Abstract :
Since the optical fiber can react to various signals, such as temperature and pressure, it is applied to many measurement cases. We measure plural tea information using the multi-functional technique with the optical fiber. First, we measure the transmissivity (depth) and liquid-level of tea by the transparency from which air and tea differ using two optical fibers, second, along with temperature change, the temperature of the tea by the transmissivity of two optical fibers is measured.
