[0019] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.
[0020] The X-ray backscatter detection device of the utility model comprises a ray source, a detector and a collimator, wherein the detectors are placed in parallel, the ray source is placed behind the detectors, and the collimator is placed between the detectors.
[0021] As a preferred embodiment of the present utility model, the detector adopts a multi-probe flexible structure.
[0022] As a preferred embodiment of the present utility model, the detector is closely attached to the surface of the object to be measured.
[0023] As a preferred embodiment of the present utility model, the detector comprises a plurality of detection units, and the plurality of detection units are installed in parallel.
[0024] As a preferred embodiment of the present utility model, the detection unit includes a rebound structure that supports up and down floating.
[0025] In a specific implementation of the utility model, as shown in FIG1 , it is mainly composed of a ray source, a detector and a collimator.
[0026] As shown in Figure 2, the conventional backscatter detection device cannot be attached to the undulating surface, while the new device can be attached to the undulating surface through a flexible structure, so that the shielding structure that originally requires a large area is reduced. On the surface of the object of the new backscatter device, X-rays are incident and scattered.
[0027] like Figure 3 As shown, multiple detection units are used inside the detector, and each detection unit has a rebound structure that can float up and down.
[0028] The utility model adopts an array-type backscatter detection structure, does not require a pen-shaped scanning device, and only requires a collimation structure and a detector, making the structural arrangement more compact and lightweight.
[0029] The detector adopts a multi-probe flexible structure, which can be closely attached to the surface of the object being measured. Compared with the traditional detection surface, the signal is better and the shielding of scattered signals is easier to achieve.
[0030] The device uses line scanning instead of point scanning, which reduces the radiation intensity requirements on the one hand, and on the other hand the sampling rate can reach milliseconds to achieve high-speed detection.

In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" refers to at least two.
