This thesis presents the basic design of the system to test the voltage of a 1 volt underwater battery at a long distance by using a fiber optic system. This system contains the voltage-to-frequency converter which converts the voltage of the battery to a variable frequency pulse train, the optical transmitter, the fiber optic receiver, and a frequency-to-voltage converter which converts the variable frequency pulse train not an output voltage. This system has small error but if we use more precise components, we can get more exact result. Additionally, the lifetime of two kinds of batteries were measured by using this circuit. Keywords include Fiber optic system Voltage-to- frequency converter Frequency pulse Optical transmitter Fiber optic receiver Frequency-to-voltage converter and Output voltage.
