【摘要】 针对目前对非球面光学零件的需求和非球面检测技术的现状，探索一种操作简便、通用性强、检测精度高的检测仪器具有重要的实用价值。 本文首先基于现阶段非球面的加工状况，提出了用接触式检测非球面的子午面面形曲线并与理论曲线相比较，从而得到非球面面形误差的检测原理，并根据该原理进行了机械结构的总体设计和电控系统的研究。电控系统采用上下位机串行通讯的控制方式，下位机以89C55为核心，驱动执行机构，并负责数据采集；上位机用VC++6.0作为开发平台，进行数据处理和图形显示。 本检测仪器采用高精度的机械构件和光栅传感器，电控系统采集、接收、处理数据正确，因而能够达到设计的检测精度要求。更多还原

【Abstract】 Aiming at the requirement of aspheric optical parts and the present state of their testing, it will have an important practical value to develop an equipment that will be easy to operate, commonly used and will have high testing precision.In this paper, on basis of the current machining state, a testing principle on aspheric surface is put forward to, the principle is a kind of touching method by testing the meridian of aspheric surface andcomparing it with the theoretical curve, so surface figure error is got.According to this principle, mechanical structure is designed andelectric-control system is researched. The electric-control system is composed of one single-chip microcomputer and one computer by serial communication. The single-chip microcomputer is 89C55, which drives executive body and does data acquisition. The task of the computer are data processing and image displaying by using VC++6.0 as software developing table.Mechanical parts with high precision and raster sensors are adapted in this equipment, electric control system can acquires, receives and processes data correctly, so this equipment can reach testing precision which is required.更多还原
