摘    要：CCD(电荷耦合器件)是一种高性能的半导体光电器件,近年来在医院、工业检测等领域里得到了广泛的应用。将CCD应用于几何量测量中,可以满足高精度测量、在线动态检测和非接触测量等的工程实际要求。在分析线阵CCD工作原理和高温辐射对CCD的影响的基础上,设计了基于CCD的钢管长度测量系统。采用双同步CCD技术,结合上位机的数据处理功能,消除了在测量过程中温度对所测长度的影响。系统测试表明,所设计的系统可以满足钢铁企业对长度的高精度测量。

Abstract: CCD(Charge Coupled Device) is a high performance semiconductor photoelectric device,and is widely applied to hospital,industrial detection and so on.Advantages of CCD in geometrical quantity measurement are high accuracy,on-line dynamic detection and non-contact measurement.Based on analysis of working principle of CCD and effect of high temperature radiation to CCD,a CCD-based length measurement system of steel pipe is designed.Owing to use of dual synchronous CCD technology and data processing function of PC,effect of temperature to measured length of steel pipe is eliminated.System test shows that the designed system can meet the need of high precision length measurement in iron and steel enterprises.
