Embodiment 1

[0036] Such as Figure 1-6 As shown, this embodiment provides a technical solution: a through-type terahertz detection device and detection method, including a device part 1 and a reflection part 3, the device part 1 and the reflection part 3 are relatively separated, and the two The separation distance is 1 meter, and a security inspection passage is formed between the equipment part 1 and the reflection part 3, and the security inspection passage is used for inspection personnel to walk and detect. The inside of the equipment part 1 is provided with a terahertz device 2, and the terahertz Device 2 has a field of view width of 1 meter and a depth of field of 0.6 meters.

[0037] The reflector 3 is provided with a first reflector 6 and a second reflector 7, an angle is formed between the first reflector 6 and the second reflector 7, and they are enclosed in the direction of the security inspection channel. The reflective surface of a reflective mirror 6 and the reflective sur...

Embodiment 2

[0052] In this embodiment, on the basis of the pass-through terahertz inspection equipment in Embodiment 1, the personnel security inspection process is as follows: Figure 7-8 As shown, after arriving at the security inspection area on normal walk, the inspected person stands facing the terahertz device 2 and leaves, stops for a moment and then continues to pass. Standing sideways is equivalent to rotating 90°, and the process of standing and turning sideways can also be completed synchronously. It takes 2 seconds to go through multiple turns and go through the entire security check and pass process.

[0053] During the security check, the terahertz device 2 performs imaging on the front side of the person (such as Figure 9 shown in the solid line area of ​​A), the first reflector 6 images the right side and the rear right side of the person (as Figure 9 Shown in the dotted line area of ​​B), the second reflector 7 images the left side and rear left part of the person (as ...

Embodiment 3

[0056] The structure of reflector 3 in this embodiment is as follows Figure 10 (a) shown. The reflection part 3 includes a back panel 31 , a main hinge 32 , a side panel hinge 34 and a connecting hinge 36 . The main hinge 32 is located in the middle of the back plate 31 and is connected to the back plate 31 and the corresponding mirror connecting plate 33 respectively. The first reflecting mirror 6 and the second reflecting mirror 7 are respectively arranged on the two reflecting mirror connecting plates 33 . One end of the connecting hinge 36 is connected to the two ends of the backboard 31, and the panel that can be freely opened and closed is wider, and is provided with fixing bolt holes to realize the different angles between the first reflector 6 and the second reflector 7. Free adjustment and fixed hold.

[0057] The angle between the first reflector 6 and the second reflector 7 in the reflector 3 is 120°, and the angle of the reflector can be flexibly adjusted by mea...

Abstract

The invention discloses pass-type terahertz detection equipment and a detection method, and relates to the technical field of security check, the equipment comprises an equipment part and a reflection part, the equipment part and the reflection part are oppositely and separately arranged, a security check channel is formed between the equipment part and the reflection part, terahertz equipment is arranged in the equipment part, the reflection part is provided with a first reflecting mirror and a second reflecting mirror, an included angle is formed between the first reflecting mirror and the second reflecting mirror, and the reflecting surface of the first reflecting mirror and the reflecting surface of the second reflecting mirror are arranged towards the direction of a security check channel, the terahertz equipment is arranged on the opposite sides of the first reflecting mirror and the second reflecting mirror, and the terahertz equipment is matched with the first reflecting mirror and the second reflecting mirror to realize 360-degree omnibearing detection on detection personnel at the same moment. According to the invention, the equipment cost and the equipment power consumption are greatly reduced, 360-degree full-coverage security check is realized at the same time, pass-type blind areas and leak detection are obviously reduced, and the security check process, the efficiency and the security check experience of personnel are obviously improved through an unshielded straight-through mode.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a through-type terahertz detection device and a detection method. Background technique [0002] Passive terahertz security inspection equipment usually needs to be equipped with an environmental control system according to its working mode and usage characteristics. On the one hand, the environmental control system provides a suitable temperature environment for the passive terahertz security inspection equipment, shields the terahertz background signal interference of the surrounding environment, and obtains a good security inspection effect; The scene ensures the scientific and efficient security inspection process and flow, and the beautiful coordination of the scene. [0003] Some passive terahertz security inspection equipment structures and methods with different shapes and structures have been reported in existing patents and literature. Such as: [0004] Ch...
