Embodiment Construction

[0025] figure 1 shows the X-ray tomography system of the present invention which is similar in structure to the related art. Specifically, the X-ray tomography system of the present invention includes a platform 10 loaded with a test object E, an X-ray source 20 for emitting X-rays to the object E loaded on the platform 10, and the X-ray source 20 that passes through the object E A magnifier 30 for converting X-rays into a visible image, a view selector 40 for selecting a certain area of ​​the image projection plane 32, and a camera 50 for acquiring an image selected by the view selector. The X-rays emitted from the X-ray source 20 are converted into a visible image before being projected onto the image projection plane 32 after being transmitted through the object E loaded on the platform 10 . Then, the view selector selects a certain area of ​​the image projection plane of the image magnifier 30 . Thus, images located within the selected area are received into the camera 5...

Abstract

The invention discloses an X-ray tomography system. The system includes a platform, an X-ray source, an image magnifier, a view selector and a camera. The view selector includes a prism and an adjustment portion for adjusting the prism to a position where an image of an area on the image intensifier image projection plane can be received by the camera. The adjustment part includes a first motor that rotates the prism in a circumferential direction of the image intensifier, and a second motor that rotates the prism in a direction perpendicular to the radial direction of the image intensifier. Therefore, the image of any area on the image projection plane can be projected. And since the optical axis of the image received by the camera is perpendicular to the camera, no image distortion occurs.

Description

technical field [0001] The invention relates to an X-ray tomography system for acquiring tomographic images of a test object, which can detect the inside of the test object which cannot be observed by naked eyes. Background technique [0002] In the manufacturing process of industrial products, in order to determine whether the product is qualified, various tests of different natures are usually carried out. Among these inspections, an X-ray tomography system is used to inspect a certain internal area that is difficult to observe with the naked eye, such as a solder connection portion of an electronic component mounted on a printed circuit board, and the like. [0003] The structure and operation of the prior art X-ray tomography system will be described below. [0004] Such as figure 1 As shown, an X-ray tomography system 1 includes a platform 10 , an X-ray source 20 , an image amplifier 30 , a view selector 40 and a camera 50 . The X-rays emitted from the X-ray source 2...
