自动调焦

然而由于目前检测系统中的工业相机一般不具有自动调焦功能，且检测mura缺陷效果较好的周期算法需要使相机镜头调节到所拍摄的FPD图像具有指定的纹理周期。

However , due to industrial cameras in the detection system generally does not auto-focus and the best method of detection of mura need to make the camera lens to adjust to the shooting of the FPD image with the specified texture cycle .
