GSJ—A型测角仪主要用于测量角度块和棱体的角度,由分度、照准、数字电路等部分组成。用圆分度的标准件代替了光学或金属度盘;用电子学细分代替了测微鼓轮;用光电自准直望远镜代替了目视望远镜;把光栅莫尔条纹、电子学细分、数字显示、光电瞄准等技术应用在测角仪上,简化了结构,提高了精度,方便了计算,为实现测量和 GSJ-A-type goniometer is mainly used for measuring the angle block and prism angle, by the indexing, sighting, digital circuits and other components. With the graduation of the circle standard parts instead of optical or metal dial; electronic subdivision replaced the micrometer drum; with optical self-alignment telescope instead of the visual telescope; the grating Moiré fringes, electronic subdivision, Digital display, optical aiming and other technologies used in the goniometer, simplifying the structure, improve the accuracy and facilitate the calculation, in order to achieve the measurement and
