利用棱镜微动理论建立望远镜光轴的检校模型
Calibration Model of the Telescope Optical Axis Based on Prism Fretting Theory
摘要
望远镜的光轴平行性是双目仪器的重要指标, 光轴失调会影响观察人员视力甚至观察效果。文章提出了利用棱镜微动理论建立望远镜光轴的检校模型, 将检校过程分为初校和精校两个步骤, 对推导过程进行了讨论。通过实验对该模型的正确性进行了验证, 结果表明, 结合CCD和图像处理技术可以对望远镜光轴进行精确校正。
Abstract
The parallelism of the optical axis of the telescope is an important indicator of the performance of binocular instruments. Optical axis disorders will affect the observers vision even the observed effect. In this paper, a calibration model of the telescope optical axis was established based on the prism micro theory, the calibration process was divided into primary correction and accurate correction and the derivation process was discussed. The validity of the model was verified by experiments, and the results show that the combination of CCD and the image processing technology can precisely calibrate the optical axis.
