The necessity for setting a axis collimator to determine the effect of irregular pivot axis and the requirement for the stability of the optical axis pointing are introduced in this paper.
本文介绍了低纬子午环设置轴准直器测定枢轴不规则影响的必要性以及对其光轴指向稳定性的要求 ,分析了存在不稳定现象的原因 ,叙述了消除不稳定现象的方法和实施的效果 ,最后给出了枢轴不规则影响的量级和修正精度。
Using uniaxial amplification system composed of a high-resolution CCD,a fast axis collimation lens and cylindrical lenses,via laser emitters imaging and facula intensity-based centroid algorithm,the "smile" of diode laser array is measured.
