How Image Intensifier Perspective Equipment Works

The x-ray image intensifier consists of an image intensifier tube, a tube container, a power supply and a bracket. The image intensifier tube is the core component, which is supported by a bracket and fixed in a tube container with anti-magnetic properties. The image intensifier tube is a large-scale high-vacuum tube. The front end of the tube is a large input screen, and the photocathode PC is close to the input screen. The tube wall has focusing electrodes G1, G2, and G3, and the tail has a small area. The output screen has an accelerating electrode A (anode) at the front of the output screen, and each electrode is supplied with the required working voltage by an external circuit. The X-ray passing through the object is projected on the input screen to generate a photon image, and the photocathode generates electrons corresponding to the brightness of the photon image to form an invisible electronic image. The image is focused by an electrostatic lens under the action of the anode electric field. It accelerates towards the anode and projects it on the output screen, producing a visible fluorescent image.
It has the characteristics of high conversion efficiency, wide dynamic range, high spatial resolution, high X-ray absorption rate in low resolution area, and strong environmental adaptability.
