摘要
本论文针对如何实现道威棱镜光轴与旋转轴平行,将道威棱镜转像理论与光学定心加工结合,提出了基于光学定心加工的道威棱镜组件装配方法。该方法根据道威棱镜旋转轴偏转时其出射光束发生变化的特性确定道威棱镜光轴,并通过车削的方式保证其镜筒外圆旋转轴与其光轴平行。本文具体提出两种道威棱镜组件定轴方案,分别为平行光管定轴方案以及激光定轴方案,此两种方案可有效保证道威棱镜反射面轴线(道威棱镜光轴)与旋转轴的平行度,定轴精度优于0.01mm。
In order to ensure the parallelism between the optical axis of dove prism and its rotation axis,a method based on the reversing image theory of Dove prism and the optical alignment machining was described.This method takes advantage of the optical property that the direction of the output beam changes with the rotation axis diversion of Dove prism to determine the optical axis of Dove prism,and ensures the parallelism between the rotation axis of cylinder with the optical axis of Dove prism by using metal-turning.Two methods which are used to determine the optical axis of Dove prism was proposed.These two methods can ensure the parallelism between the reflecting surface axis of dove prism and its rotating axis,and the accuracy of axis determining is better than 0.01 mm.
