数字图像技术在中心偏测试仪中的应用

Application On Digital Image Technology In Decentration Measuring For Objective Lens

CCD接收十字分划板的光学成像,中心偏测试软件处理处理由图像采集系统提供数字图像。借助于数字图像技术,中心偏测试系统通过非接触测量,完成自动聚焦,定位图像中十字中心的位置。这种方法提高了测量精度和工作效率,取得了较好的应用效果。

CCD receives the optical imaging of Cross Divisional Board. The decentration measurement software processes the digital image provided by Image Acquisition System. With digital imaging technology , the measurement instrument completes automatic focusing and locates the Crosshalr by non - contact measurement. The method improves the measurement accuracy and efficiency and achieves a better effect.
