Apparatus and method for inspecting mobile target

Abstract

Disclosed are an apparatus and method for inspecting a mobile target by using fast imaging. A control unit powers on a betatron in order to enable the betatron to be in a standby state when receiving a detection signal, from a first position sensor, indicating that a mobile target enters a channel. When a second position sensor detects different sections pass by a radiation scanning region, the control unit controls the beam-emitting time point and beam-emitting mode of the betatron in order to correspondingly inspect each section of the mobile target travelling at non-uniform speed and controls the reconstruction of a scanning image according to the moving speed, received from a speed sensor, relative to the mobile target, and corrects scanning image data according to the moving speed. Accordingly, inspection is performed when a vehicle moves and a driver and passengers are not required to get off. The apparatus controls the betatron to emit a ray beam with corresponding energy at an extremely fast speed in order to scan the mobile target when the mobile target passes by the scanning region, and achieves a flexibly scanning mode so as to greatly shorten inspection time.

Description

technical field [0001] The invention relates to a scanning and imaging process of a moving target, in particular to a device and method for imaging and checking a moving target. Background technique [0002] Equipment for inspecting vehicles using high-energy rays is a typical example of equipment for imaging inspection of moving objects. In the equipment for inspecting vehicles with high-energy rays, the vehicle to be inspected is usually driven by a drag device to move at a constant speed, and the accelerator continuously emits high-energy rays with a fixed frequency. This equipment has a baffle that can shield the ray, and whether the high-energy ray shoots to the vehicle under inspection is controlled by the baffle. When the baffle is opened, high-energy rays are emitted to the object to be inspected, and the vehicle is scanned and imaged for inspection. [0003] In this kind of traditional equipment, since the accelerator is always on, the power consumption is large; ...

AI Technical Summary

Problems solved by technology

[0003] In this kind of traditional equipment, since the accelerator is always on, the power consumption is large; and the temperature of the equipment is always high, which requires a large cooling equipment and takes up a lot of space; and long-term startup affects the service life of the accelerator, so that Product cost is high; and there are dark electrons in the accelerator all the time, which is potentially dangerous

At the same time, because the opening and closing of the mechanical baffle is used to control the emission of high-energy rays, the response speed is slow, which makes the inspection time longer and the vehicle inspection rate is low.
