Embodiment Construction

[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Specific embodiment one of the dual-ray source detection device of the present invention, such as Figure 1~8 As shown, it includes a side illuminating unit and a top illuminating unit and a control system for controlling the side illuminating unit and the top illuminating unit. The side illuminating unit and the top illuminating unit respectively contain a radiation source, and the object to be detected is detected through the radiation source. Therefore, the detection device of the present invention is called a dual-ray source detection device. Of course, the two irradiation units of the dual-ray source detection device are not limited to one being a top irradiation unit irradiating from the top of the object to be inspected, and the other being a side irradiation unit irradiating from the side of the object to be inspected. In other embodiments...

Abstract

The invention provides double ray source detection equipment and control equipment and a beam emergent method thereof. The beams are emergent by two ray sources through pulses and the beam emergent moment of the two ray sources is staggered in case of beam emergent of the double ray source detection equipment. Therefore, the two detector arrays do not receive the rays scattered by the other ray source when the two detector arrays receive the rays emitted by the corresponding ray source so that the scattering interference between the two detector arrays can be completely and effectively eliminated and the imaging effect can be enhanced; meanwhile, the shielding device does not need to be arranged between the two detector arrays for shielding and the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of detecting objects by using rays, in particular to a dual-ray source detection device, its control device, and a beam output method. Background technique [0002] In places such as customs, docks, airports, logistics parks, and high-speed checkpoints, it is generally necessary to conduct inspections of contraband or other purposes for incoming and outgoing cargo boxes. The commonly used detection equipment is mostly radiation source detection equipment. The radiation source emits high-energy radiation to penetrate the container to be detected, and then receives the radiation that penetrates the cargo through the detector installed on the opposite side of the radiation source, and forms a display through the detected radiation. An image of the contents of the container to detect the container. The detection principle of ray detection equipment is as follows: Figure 8 As shown, X-rays generated by accelera...
