附件化准直目镜与投射器的设计

摘要

One method is introduced to realize high accuracy auto collimation for mapping instruments via adding accessories without a refit. Collimating ocular is used for close quarters auto collimation, while projector is used for far-forth quarters auto collimation. Moreover, the design and analysis are referred to concretely, expanding the using range of mapping instruments in effect.%阐述了不需改装仪器,以增加附件的形式使通用大地测绘仪器具有高准确度自准直功能的方法,近距离自准直采用准直目镜,远距离采用投射器,并针对性地提出了具体的设计方法和分析比较,有效拓展了仪器的使用范围.
