aberration

In view of the light reading of DJ6-tpye optical transist, based on practical work, this article systematically analyses the reasons of the optical parallax and aberration caused by this kind of optical instruments, and it also shows us some methods to deal with them according to the principles of geometrical optics.

针对DJ6型光学经纬仪的读数光路,从几何光学原理出发,结合工作实际,系统地分析了该类仪器视差和行差产生的原因,并提出了相应的处理方法。

To avoid or weaken the influence of the secondary image which is from the optical system,analyzed the reason about the secondary image when the reverberation of the center reflector in the optical system and whether have the parallel error or not in this text.

视准式光学系统瞄准具的成像有主像和副像两种情形,主像是对目标瞄准的必要标志,副像则对目标的瞄准产生不良影响,为消除或减弱光学系统所成的副像对瞄准精度的影响,主要分析了光学系统中中心反射镜的反射和有无平行差时产生副像的原因。

The phenomenon described in the title is interpreted by the angle changing from acute to obtuse in the aberration formula.

对光行差公式中钝角变成锐角的现象给出了物理解释 ,澄清了“从前面看到了从后面来的光”的模糊图像 。

This paper introduces the formation and changes of diurnal aberration and annual aberration and compares in simple language the difference of directions between annual aberration and annual parallax and the difference of time when extremes emerge.

介绍了周日光行差、周年光行差的形成与变化。

According to the above mentioned assumptions a general focussing lens calculation formula of run error is deduced.

在这两个假设前提下,推导出调焦透镜运行差计算通用公式。
