A coupler adds the polarization-adjusted reference light signal to an input light signal of a state of polarization. A branch means branches a part of the added signal, and a light detecting part(530) detects a beating signal of an output signal of the branch means. An amplifier(540) amplifies the detected beating signal, and an analog-to-digital converter(550) converts the amplified beating signal into a digital signal. A micro control unit(560) and a serial port(570) process the digitized beating signal.
