【Abstract】 The principle and the construction of Laser Beacon are presented in detail, servo-control circuits in the instrument is analysed. It can automaticully adjust horizontal and vertical reference plane by using liquid angular sensor and continuously emit accurate reference plane with a radius of 300 meters(in range of 360°).The main technical parameters are as following: Laser emitter:He-Ne Laser; power: 2mw; datum beam: <16 mm; scanning speed: 0～12 r/s; vibrating of light beam: ≤1‰.更多还原
