摘要
介绍了一种CRT显示管分辨率自动测量系统,可以对CRT显示管的线宽进行快速准确的测量。该系统采用面阵CCD摄像机做为传感器,具有自动光学聚焦和投影管聚焦电压自动调整功能,有效地提高了系统的测量精度和测量速度。
A automatic resolution measurement system of Cathode Ray Tubes （CRT）, display tubes has been developed. The width of a scanning line displayed at screen can be measured accurately and quickly by an area array Charge Coupled Device （CCD） camera with a microscope lens. The system has voltage auto-adjusting functions of optics focusing and CRT＇s focusing. Measuring results show that the auto-adjusting improves the precision and efficiency of the measurement effectively.
