What is the working principle of x-ray inspection equipment?

X-RAY Nondestructive Testing X-ray (hereinafter referred to as X-Ray) uses a cathode ray tube to generate high-energy electrons to collide with a metal target. During the collision, the electrons suddenly decelerate, and the kinetic energy lost will be in the form of X-Ray It emits, which has a very short wavelength but high electromagnetic radiation.

X-ray inspection equipment penetrates the sample to be inspected by light, and then maps an X-ray image on the image detector. The image formation quality is mainly determined by the resolution and contrast, and the resolution of the imaging system depends on X-rays.

1. Basic summary

X-ray inspection equipment penetrates the sample to be inspected by X-ray, and then maps an X-ray image on the image detector. The quality of the image is mainly determined by the resolution and contrast. Generally speaking, the light pipe of the x-ray detector Performance plays a very important role. All x-ray equipment uses Hamamatsu HAMAMATSU imported from Japan as the core components.

2. X-ray tube

The x-ray tube mainly provides electrons from the hot cathode through the electric field to accelerate to the anode. When electrons are rapidly accelerated to a high-speed state under a high voltage of tens of kilovolts, kinetic energy is converted to release X-rays when they hit the anode body. The size of the collision area is the size of the X-ray source. Through the principle of small hole imaging, we can roughly know that the size of the X-ray source is inversely proportional to the definition, that is, the smaller the x-ray source, the clearer the image.

3. X-ray detector

X-ray detectors make up for the shortcomings of chemical film imaging in the past. The detectors can save costs and improve efficiency.

Because of the differences in the density and thickness of the inspected items, after the X-rays released by the x-ray inspection equipment penetrate the inspected items, the degree of absorption of the rays by the object is also different, and the amount of X-rays that eventually reach the fluorescent screen is also Different, through the imaging principle, different black and white images will be formed on the phosphor screen. Next, you need to use professional equipment to collect the image, and analyze and process the image, and finally get a clearer image.
