摘　　要：采用摄远物镜与显微物镜组合技术在小尺寸条件下实现了大的物镜焦距,确保了瞄准分辨力和对准精度。设计了一种新颖的“A”字型分划板,既能用作准直目标,又可以供线阵CCD进行双坐标角度测量。装置与多齿分度台、多面棱体等配合使用,可以完成经纬仪主要性能指标的快速检测。A technique of combining tele-objective with micro-objective is used to realize large objective focus and to assure aiming resolution and precision. A novel 'A'-type divisional board is designed, which can be regarded as aiming target and can also be used to measure double coordinates angle by single array CCD. The Device cooperating with the multi-gear graduation platform and the multi-side prism can quickly measure the main performance index of theodolite.
