大批量生产望远物镜的自动测量

Automatic Measurement for a Big Batch of Telescopic Objectives

本文主要介绍一种利用ＣＣＤ器件作探测器，具有自动定焦功能的望远镜物镜自动测量装置。介绍了测量原理，光电自动定焦问题，减小和消除误差的方法。提出了一种确定刻线像中央峰值位置的方法。文中还介绍了这些技术的程序框图。

This paper briefly describe an automatic measuement equipment, which have the capability of photoelectric automatic defocusing with CCD sensor. It introduce the principles of measuring and photoelectric automatic defocusing, and the methods of decreasing errors. In this paper, have provided a method of determing central peak of imaging of the slit. And also describe the program frames of these methods. Finally, it introduce other capabilities of the equipment.
