【Abstract】 A novel method for measuring two dimensional small angle by means of the single linear CCD and the principle of auto collimation is presented in the paper, in which the single linear CCD is used to trace and measure simultaneously two dimensional small angle with the high measuring frequency.Measuring principle of the single linear CCD two dimensional auto collimator is proposed, and its hardware and software are designed. The experiment shows that the measuring accuracy of this instrument is better than 1 arcsecond within ±5 arcminute range, with a measuring resolution better than 0.3 arcsecond.更多还原
