摘　　要：针对目前激光扫平仪校正效率低这一问题,设计出了一种数显式激光扫平仪校正台,介绍了这种新型校正台的原理、结构、调整方法,并对其误差进行了分析。这种新型校正台采用了线阵CCD和双平面旋转反射镜组合的独特形式,使校正台在实现数显的同时,具有结构紧凑、调校快速方便的特点,扫平极限误差达到±0.153mm/m。A kind of correcting platform for laser scanning level device with digital display is designed with an aim at solving the low correcting efficiency in the existing laser scanning level device. Also,the working principle,structure and adjustment method of the new type of correcting platform are described,whose errors are analyzed in this paper. The unique combination of line area CCD with double-plane revolving reflection mirror is adopted in the new type of correcting platform,thus making the correcting platform be compact in structure,fast and convenient in correction when the digital displays are achieved. Accordingly,the scanning level limit errors can reach ±0.153 mm/m.
