[0002] Industrial CT is a non-destructive testing technology used to obtain a three-dimensional image of the internal structure of an object. This technology usually uses X-rays or other penetrating radiation to scan the object and reconstruct the internal structure of the object by analyzing the data collected from different angles. X-ray grating devices are one of the key components in industrial CT systems. It is used to control the direction and intensity of the X-ray beam so that it can accurately irradiate specific areas of the object during the scanning process. X-ray grating devices play a key role in industrial CT systems. By controlling the direction and intensity of the X-ray beam, high-precision imaging of the internal structure of the object can be achieved.
