Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] This scheme is based on the principle of Compton scattering to realize the detection of scattering arrays from two or more different viewing angles based on a radiation source, forming a stereoscopic viewing angle to receive scattering signals for judging the distance and spatial position of objects; Detect Radiation Imaging.

[0028] To this end, this scheme specifically uses a stereoscopic perspective scattering array detector based on the Compton scattering principle to form a stereoscopic perspective scattering array detection system, so as to realize the stereoscopic perspective scattering array detection of security inspection objects and form a stereoscopic perspective radiation image.

[0029] see figure 1 , which is a schematic ...

Abstract

The invention discloses a stereo visual angle scattering array detecting system and a method thereof. The system and the method are based on a radiation source. A stereo visual angle scattering arraydetector based on a Compton scattering principle is utilized for performing scattering array detection of the stereo visual angle on a checked object, thereby forming a stereo visual angle radiation image. The stereo visual angle scattering array detecting system and the method thereof have advantages of reducing misjudgments and checking omission caused by overlapping of checked luggage, reducingtechnological development difficulty of safety checking equipment, reducing manufacturing cost of safety checking equipment, and settling a problem of overlarge integral size.

Description

technical field [0001] The invention relates to X-ray imaging technology, in particular to detector technology. Background technique [0002] In the field of radiation imaging detection, Compton scattering imaging technology has obvious characteristics and irreplaceable advantages. For example, the spatial layout of the scattering detector is relatively flexible, and the detection sensitivity to low atomic number substances is high. [0003] From the perspective of the use in the field of security inspection, backscatter imaging is mainly used as an auxiliary means to cooperate with the perspective imaging inspection work of security inspection, such as the XT11-064Ⅱ drug detector produced by the Third Research Institute of the Ministry of Public Security. [0004] Moreover, in order to reduce misjudgments and missed inspections caused by overlapping luggage, most security inspection equipment reduces misjudgments and missed inspections caused by overlapping luggage by incr...
