| Abstract: | -A new method of measuring rotary eccentricity by means of optical heterodyne is described, by which the eccentricity of some rotary subjects, such as turnplate, rotator and so on, can he measured dynamically and precisely. The experiment has been done with CO2 laser as local oscillator and turnplate as analog target. The requirements for measurement are given and analyzed. |
