摘　　要：光电经纬仪工作前,要对经纬仪的方位测量基准进行标校,安装在陆地的经纬仪通常以正北作为方位测量基准。而舰载光电经纬仪的方位测量基准是舰载的艏艉线方向。专业的测量舰船设有独立的用于光电经纬仪的标校系统,普通的测量舰船没有设置单独的标校系统,只设有指示舰船艏艉线的平面基准镜,平面基准镜的法线方向即是舰船艏艉线方向。为了将舰船艏艉线平面基准镜的法线方向通过光路折转的方法转到光电经纬仪的光学主系统视轴上,设计一种方位基准标校装置。该标校装置由两个自准经纬仪和两个折转光管及辅助固定支架组成。标校时可在测量舰船上临时安装,标校工作结束后即可拆除,安装、拆除工作简单易行。折转光管的结构简单,便于保管运输。The azimuth reference of the electrical-optical theodolite should be calibrated before working, which is the north direction generally used ground basis. However,the azimuth reference is the keel-line direction on ship. There is the self-contained calibration system for the photoelectric theodolite on the technical measuring ship, but none on the universal measuring ship except a reference mirror, the normal line of which instructs the keel-line direction. In order to instruct the light from the normal line of the reference mirror to the primary optical axis of the theodolite,an equip-ment of calibration is designed. The equipment is comprised of two self-collimating theodolites and two deflective light tubes,as well as the aided structures. It is easy to mount temporarily when calibrating on ship and demolish after that. The structure of the deflective light tube is simply constructed,and it is easy to store and transport.
