Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] A kind of X-ray camera disclosed by the present invention, such as figure 2As shown, it is formed by coupling the light cone 1 with the CCD or CMOS camera 3, that is, the small head of the light cone is bonded with the photosensitive surface 2 on the CCD or CMOS chip through optical coupling glue, and the other end of the light cone is plated with Needle-shaped CsI crystal 4, moisture-proof film 5, aluminum film or silicon nitride film 6, the light cone 1 is formed after being drawn by a high-refractive-index core glass rod and a low-refractive-index skin glass tube used in ordinary light cones On the basis of the fine glass fiber array, a black glass leather tube or a glass tube made of glass material that can be blackened after the subsequent process is put on before the monofilament is drawn. For the convenience of descrip...

Abstract

The invention discloses an X-ray camera and a manufacturing method thereof. It is formed by coupling a light cone with a CCD or a CMOS camera. The large head of the light cone is sequentially a needle-shaped CsI crystal, a moisture-proof film, an aluminum film or a silicon nitride film; The light cone is based on the high refractive index core material of the ordinary light cone covered with a low refractive index leather material, and then covered with a black glass or lead silicate glass sleeve with matching thermal and physical properties. The previous process of the fiber optic panel produces a fiber array cylinder, and then the light cone is drawn according to the ratio of the small and the small ends. The light cone made of lead silicate glass sleeve needs hydrogen reduction treatment; the large head of the above light cone is sequentially After the needle-shaped CsI crystal, moisture-proof film, aluminum film or silicon nitride film is produced, the small head of the light cone is coupled with the photosensitive surface of the camera through optical glue. The X-ray camera thus produced has a minimum pixel of 5 μm, a resolution above 30 lp / mm, and a good MTF.

Description

technical field [0001] The invention belongs to the technical field of X-ray imaging, and mainly relates to a high-resolution X-ray camera and a manufacturing method thereof, in particular to a light cone coupling CCD or CMOS camera and a manufacturing method thereof. Background technique [0002] Since the discovery of X-rays by German physicist Roentgen in 1895, X-ray photography and dynamic imaging have been widely used in the fields of medical and industrial imaging. With the continuous improvement of the quality of CCD and CMOS devices and their wide application in the industrial field, high-resolution, digital and remote diagnostic X-ray CCD or CMOS cameras provide a strong technical support for medical imaging and industrial non-destructive detection. And it is possible to replace traditional X-ray imaging equipment. The equipment that converts X-rays into digital images in the field of medical imaging is called DR (Digital Radiography), which is a general term for v...
