A first detector that receives and detects 3-tone signals of three patterns of a first 3-tone signal obtained by combining three waves of angular frequencies ω1, ω2, and ω3 (here, ω2−ω1=ω3−ω2=Δω is established), a second 3-tone signal in which each tone has a phase offset, and a third 3-tone signal having a phase offset different from the phase offset of the second 3-tone signal, a BPF that allows only a beat component of an angular frequency difference Δω between adjacent waves of the 3-tone signals among signals output from the first detector to pass, a second detector that detects power of the beat component that has passed through the BPF, a voltmeter that measures a voltage of a signal output from the second detector, and a phase calculator that calculates a phase based on the measured voltage values of the three patterns.
