The core technology of an X-ray detection system is based on the principle of X-ray interaction with matter. When X-rays penetrate an object, materials of different densities and thicknesses absorb and scatter them to varying degrees. High-density areas (such as metals) absorb more rays, while low-density areas (such as air or plastics) allow more rays to pass through.
X-rays are generated by an X-ray tube-when a high-voltage current passes through the cathode, electrons are accelerated and strike the anode target, thus generating X-rays. After these rays penetrate the object being inspected, they are captured by the detector and converted into electrical signals, which are then processed by a computer to generate an image of the internal structure. It typically consists of five core components: an X-ray source, a detector, a sample stage, an image processing system, and a control system. These components work together to achieve high-resolution, high-precision detection capabilities.
