Neutron transmission imaging system for prefabricated wall detection and application thereof

The invention discloses a neutron transmission imaging system for fabricated wall detection and an application thereof, and relates to the technical field of nondestructive testing. The system comprises a neutron transmitter assembly for transmitting fast neutrons and a neutron receiver assembly for receiving thermal neutrons, which are arranged at two sides of a detected fabricated wall. The neutron transmitter assembly and the neutron receiver assembly are fixedly installed on a first driving device and a second driving device respectively, the first driving device and the second driving device can drive the neutron transmitter assembly and the neutron receiver assembly to move on a vertical plane parallel to the vertical plane where a detected fabricated wall is located, and then two-dimensional planar motion is achieved. The neutron receiver assembly is connected with the second driving device, and the first driving device and the second driving device are connected with the main control device. Meanwhile
