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; ...
