[0002] The scintillation crystals used in industrial CT are mainly NaI crystals. In industrial CT, scintillation crystals are one of the core components of the detector. Industrial CT is a non-destructive testing technology, which is mainly used to detect the internal structure and defects of objects. Its basic principle is to use X-rays or other radiation sources to scan objects, and the detector receives and records the transmitted radiation. The scintillation crystals in the detector will emit light signals after receiving the radiation. These light signals are then converted into electrical signals, and processed by the image reconstruction algorithm to obtain the internal structure image of the object;

[0003] When the scintillation crystal detector scans and detects an object, the object needs to be placed on the detection end of the scintillation crystal detector. When there are many objects that need to be detected, the objects need to be placed on the detection end of the scintillation crystal detector one by one, and the objects need to be taken away after the detection is completed. This detection method has low detection efficiency and is prone to increase labor intensity. Summary of the invention
