研制了采用准直激光束作为测量基准轴线、阵ccd光电器件作为位置传感器、单片机进行数据采集、理与测量结果显示的直线度自动检查仪。

• A straightness automatic tester is developed in which the aligned laser beam is used as the measuring datum axis, a linear matrix CCD is used as the position sensor, and a chip microcomputer is used for data acquisition and processing as well as displaying measuring results.
