Graduate School of Chinese Academy of Sciences,Beijing 100390,China) Abstract: autocollimator is the equipment which test variance of beam and act an important part in optical an fine machine testing. Based on communication protocol of autocollimator empoldering a system which can be working on the same timer with other equipment.. the system can meet the needs of special condition and can remote control the autocollimator, which make working more intelligent.
