    The several measurement methods of beat-wave interference fringe fraction used in beat-wave interferometer are described. The principle of the beat-wave phase-locked type of aiming technique is proposed. The three principle schemes of the beat-wave interferometer are presented. The measurement accuracy and some other problems are discussed and compared.
