Problems solved by technology
[0003] However, the existing detection devices based on backscatter imaging technology often have poor portability due to complex structures and large volumes.
Moreover, the detection device needs to adjust the intensity of the radiation according to the thickness or depth of the measured object. The existing detection device based on backscatter imaging technology has a complicated adjustment process for the radiation intensity and is not easy to operate.

The invention relates to an emitting device based on a back scattering imaging technology. The emitting device comprises a source container and a collimator arranged on the source container, wherein a collimating hole in the collimator is communicated with a ray outlet formed in the source container; the source container comprises a rotor provided with two or more straight through holes with different cross sectional areas, and a driving shaft; the axles of the two or more straight through holes are positioned in the same plane; the inside of the source container is provided with a holding cavity and an accommodating cavity communicated with the holding cavity and used for accommodating ray sources; the accommodating cavity and the ray outlet are positioned on the same plane; the rotor is rotatably held in the holding cavity; the driving shaft passes through the source container and is in driving connection with the rotor; the driving shaft drives the rotor to rotate; the rotating plane of the rotor is parallel to the same plane. By rotating the driving shaft to drive the rotor to rotate and selecting the straight through holes with proper cross sectional area from the two or more straight through holes with different cross sectional areas, rays pass through the straight through holes, the emitting intensity of rays is adjusted, and the operation is simple and easy.
Description
technical field [0001] The invention relates to the technical field of backscatter imaging detection, in particular to an emission device based on backscatter imaging technology. Background technique [0002] Backscatter imaging technology is a new type of non-invasive imaging technology based on the Compton scattering effect, which has been used in industrial flaw detection, hidden object search, border security inspection and other fields. Backscatter imaging has three advantages over other imaging techniques. (1) The emission device for outputting rays and the detection device for receiving and detecting the rays output by the emission device can be placed on the same side of the measured object at the same time, so backscatter imaging is suitable for detecting radiation that is difficult to penetrate by traditional X-ray transmission technology. transparent large objects and objects hidden inside walls or underground. (2) Backscatter imaging is particularly sensitive t...
