摘　　要：介绍了一种利用吊镜进行电子水准仪i角的检测方法,在吊镜双摆位误差调至零后,可以形成等高的条码尺像,这样一来可以将测量场地长度缩短至一半,同时也可以免去换站整平对中的工作,在一个测站上就可以完成整个i角校准工作,且吊镜成本较低,溯源方便。该方法也可配合五棱镜对激光垂准仪的上激光点铅垂度进行校准。This paper introduces a method of measuring i angle of electronic level by hanging mirror,after adjusting the double setting error of the suspension mirror to zero,it can form bar code image of equal height.In this way,the measuring site can be reduced to half,at the same time,the work of leveling and aligning stations can be avoided,the whole i angle calibration can be completed on one station,and hanging mirror cost is low,traceability is convenient.This method can also be used to calibrate the upper laser point plumbness of laser vertical collimator with pentaprism.
