Abstract

The main components of the device are three optical tubes. The upper tube and lower tube are two mini autocollimators. The middle tube is a mini autocollimator with two-dimensional small angle synchronous measurement function. The optical configuration of each tube and the processing circuit of the middle tube have been described in detail. In order to simplify the design of the middle tube, we proposed a double-lamp and double-reticule measurement mode and place all the reticules on refraction routes to improve recognition precision of the CCD acceptor. The principle of two-dimensional angular measurement using "N" reticule and one linear CCD has been introduced. We also proposed a subdivision method of small angle measurement to control the ultimate error within 0.5". Using the middle tube itself or combining it with the other two tubes, we can verify all the main performance parameters of the existing optical aiming equipments. The measurement uncertainties have been evaluated at the end of the paper. The results show that the measurement uncertainties of the device can fully meet the requirements of verification work. The device has the advantages of small volume, high automation, convenient verification operation and good reading repeatability. It has been used in some measurement stations successfully.
