低位数线阵CCD高精度非接触尺寸测量

High Precision Noncontact Dimension Measurement Using Linear Array CCD with Fewer Elements

摘要: 从提高测量精度、增大测量范围、经济、实用的角度出发,本文分析了常用的两种线阵CCD非接触尺寸测量方式存在的问题,提出了"单眼"单端扫描测量方式,并设计出了适合测量应用的线阵CCD驱动电路和计算机通用接口。通过实验,证明此方法是行之有效的。

Abstract: In order to improve the precision and range of measureme nteconomically and practi-cally, this paper discusses the problems of the common method of noncontact dimensionmeasurement using linear array CCD. A "simple eye-single end scanning" measurementmethod is proposed. A practial linear array CCD driver-circuit and computer generalinterface has been obtained. The experiment results given in this paper indicate that thenew method is available.
