In this paper an important principle—adaptive principle is analyzed systematically. Then a dual-frequency laser coaxality measurement system is presented. In this system the distance between two interfering beams is less than spot radius, so this makes the system quite resistant to air turbulence, and the measurement is not affected by laser beam drift. Therefore it is fitful to straightness and coaxality measurement of long range (30 meters).
