Many customers will ask a lot of technical parameters and other questions when asking about image intensifiers. Why not, let us learn about this device in this article. The first thing we need to understand is the working principle of the image intensifier, so what role does the working principle of the image intensifier play in imaging?
First of all, we need to be clear about the structure and purpose of the input screen, photocathode, focusing electrode and output screen of the image intensifier. The photocathode inside the phosphor screen generates different numbers of photoelectrons according to the intensity of the fluorescence. The photoelectrons of the photocathode are attracted by the positive potential of the anode and fly to the positive charge at high speed. The photoelectrons pass through the anode hole and are projected onto the output screen to produce a visible image. This image is brighter and smaller in size than the previous perspective image. When X-rays pass through the human body, X-rays of different intensities are projected onto the input screen according to the different densities of human tissues.
The above is an introduction to the working principle of the image intensifier. If you have any questions about the working principle of the image intensifier or need such a device, please contact us.
