Application of image intensifier: It is mainly used in image enhancement of low-dose X-ray machines, so that very low X-rays pass through the measured object to form valuable images through the electron multiplication of image intensifiers, thereby reducing the impact of X-rays on users. s damage. Safe to use, light and high resolution, you can see clear images without the need for a dark room. The dose of radiation leakage is low, and no protection is required. It is a necessary testing equipment for hospitals. At the same time, it can also be used as on-site diagnosis for athletes and military field personnel when encountering injuries, non-destructive testing in industrial sectors, security inspections in security departments, customs, and post and telecommunications departments. The reason why impact intensifiers are used on X-rays is because with the development of these impact devices. Both the resolution and exposure time of the camera have been greatly improved. However, the complex industrial environment often results in suboptimal target images. We also need to use image enhancement techniques to further process the image for better features and visual effects. According to the space in which the enhancement process is located, general image intensifier methods can be divided into methods based on spatial domain and frequency domain. Airspace-based methods process images directly. The method based on the frequency domain is to correct the transform coefficients of the image in a certain transform domain of the image, and then inversely transform it to the original spatial domain to obtain an enhanced image. The main purpose of the effect enhancer is to improve the visual effect of the image and the clarity of the image to achieve the best use effect.
