Abstract

A measuring apparatus for contactlessly measuring vibration or displacement of a measurement target includes a light source configured to emit a continuous wave of light frequency-modulated to arrange a measurement site of the measurement target within a correlation peak, a divider configured to divide the continuous wave of light into first and second divided-waves of light, a light receiver configured to receive interfering light of the first divided-wave of light reflected by the measurement target and the second divided-wave of light, and a calculator configured to calculate the vibration or displacement of the measurement target using an electric signal output from the light receiver.
