Generally, the width of the substrate detectable by a light detecting device is between 400 mm and 5 ,. Therefore, when performing surface detection of a large-scale substrate, the displacement of the upper and lower directions can be performed by moving a photodetecting device (eg, 3A, 3B, or not, or by moving two photodetecting devices for displacement in the up and down direction (as shown in Figs. 4A and 4B). When using a light detecting device to detect the substrate, in order to improve the accuracy of the detection 1, generally every time the moving light detecting device is displaced in the up, down, left, and right directions, the incident angle, the reflection angle, the wavelength, the intensity, and the scattering of the light are adjusted. And the direction of polarization to optimize the optical condition of the object under test. However, the conventional substrate photodetecting device has the following defects: ^, (a), first, as shown in Figs. 3A and 3B, the method of detecting a large-sized substrate by the upper and lower left and right displacement photodetecting devices, due to photodetection The device can only illuminate a part of the substrate at a time, and often lengthens the inspection time of the large-sized substrate, and the substrate is cut into multiple regions in sequence, and is not detected.
