  • Patent number: 11816766
    Abstract: A super-resolution X-ray shadowgraph system includes an X-ray source, a sample stage, an X-ray detector and an image reconstruction device, which are arranged in sequence. Geometric centers of the X-ray source, the sample stage and the X-ray detector are collinear. The geometric center of the sample stage is provided with a through hole for placing a testing sample, the X-ray source is used for providing X-rays, and the X-rays penetrate the sample stage to form an image on the X-ray detector. The image reconstruction device is used for acquiring the image and performing an image reconstruction on the image to obtain a new image. The shadowgraph system and the imaging method therefor can overcome a deficiency of a lower resolution of the image limited by a size of the source, thereafter obtaining a clear shadowgraph with a high resolution.
