Abstract: An apparatus for measuring a length of an optical resonant cavity includes a frequency tunable light source, a beam splitter, a frequency modulator and an optical resonant cavity. The frequency tunable light source emits a beam. The beam splitter is disposed on the optical path of the beam for dividing the beam into a first beam and a second beam. The frequency of the second beam is modulated by the frequency modulator to differ from the frequency of the first beam by a beat frequency. The optical resonant cavity is disposed on the main optical path of the first beam and the main optical path of the modulated second beam. The first beam and the modulated second beam enter the optical resonant cavity for measuring a length of the optical resonant cavity, and a variation in cavity length is calculated from the beat frequency.
