【Abstract】 A method for measuring two-dimensional small angle by means of the matrixCCD and the principle of auto-collimation is presented and analysed, and its software controlledby computer is designed in order to realize high-speed data capturing and processing, and theinterface displays the measured data in real-time through Visual C++. The experiment resultsshow that the measuring error of this instrument is better than 0. 7 arc second within 3 arc minuterange, with a measuring resolution better than 0.1 arc second.更多还原
