The structure and principles of an optical non-contact measuring system of large-dimension diameter were analyzed detailed in the paper. This system can be used to measure up to the diameter of 2200 millimeters. And it also can be used to measure the coaxiality of inner and outside of cirque. Moreover, the system can realize measure on-line parameters in processing. The ultimate errors in measuring large-dimension diameter are less than 0.02 millimeters.
