| Abstract: | An electromagnetic driving micro-mechanical unit is designed and automatic tracking from photoelectric signal of two-dimension autocollimator is realized. The measuring accuracy of the instrument is improved by means of separation tracking from readings. The practical testing and operation show that the design is reasonable and the instrument is reliable. The operating range (stoke) of 2-D coordinate is -110" - +100". The instrument has an actual zero point and its resolution is 0.1". Both the pointing and locating accuracy are 0.1" and nonlinear error is less than 0.5". |
