Abstract: A laminography system includes a table, an X-ray source, an image intensifier, a view selector and a camera. The view selector has a prism for refracting a ray of light, and an adjusting part for adjusting the prism to a position in which images at a certain area of an image projecting plane of the image intensifier are received into the camera. The adjusting part has a first motor for rotating the prism along the circumferential direction of the image intensifier, and a second motor for rotating the prism in a direction perpendicular with respect to a radial direction of the image intensifier. Accordingly, the images at any areas of the image projecting plane of the image intensifier can be obtained. In addition, since an optical axis of the image passing through the prism and then received into the camera is in perpendicular relation with the camera, no image distortions occur.
