摘要：A measuring apparatus for contactlessly measuring vibration or displacement ofa measurement target includes a light source configured to emit a continuous wave oflight frequency-modulated to arrange a measurement site of the measurement targetwithin a correlation peak, a divider configured to divide the continuous wave of light intofirst and second divided-waves of light, a light receiver configured to receive interferinglight of the first divided-wave of light reflected by the measurement target and thesecond divided-wave of light, and a calculator configured to calculate the vibration ordisplacement of the measurement target using an electric signal output from the lightreceiver.
