【Abstract】 Errors in the laser rotating level are analyzed and its expression in trigonometric function is presented. A new optoelectronic auto-tester of the errors in the laser rotating level is introduced, which can work efficiently and flexibly. It is proved theoretically and practically that the uncertainty of the angle measurement of the auto-tester is better than ±2″, and the resolution ±1″.更多还原
