Abstract:

The paper describes a compact two-coordinate photoelectric digital autocollimator made using a single linear charge-coupled photosensitive device and a special type of autocollimation mark. The autocollimator allows us to measure angles in the horizontal and vertical planes in the range of ±10^′. In this case, the maximum error in measuring the angle in the horizontal plane does not exceed ±0.7^′′, and in the ±7.5^′ angle measurement range, it does not exceed ±0.5^′′. The maximum error in measuring the angle in the vertical plane does not exceed ±5^′′. The frequency of the output of digital angle measurement data by the autocollimator is 30 Hz.
