Manufacturing process of novel X-ray raster

Abstract

The invention discloses a manufacturing process of a novel X-ray raster. The manufacturing process comprises the following steps of S1, metal plate grinding; S2, composite film manufacturing; S3, composite film pack manufacturing; S4, cutting and S5, packaging. According to the manufacturing process, a heavy metal plate and a light metal plate are machined through the physical rolling technology,preset thickness is obtained, and the machining process is simple. A conventional metal cutting method, such as laser cutting, is adopted, the composite film pack is cut, and the thickness of the cutcomposite film pack is controlled through the number of the composite film pack. The duty ratio of the raster is adjusted through the thickness proportion of the heavy metal plate and the light metalplate, and the effect of the raster is adjusted through different duty ratios. The cutting process and the packaging process can be quantified, machining is convenient, and a large number of rasters can be produced at a time.

Description

technical field [0001] The invention relates to the technical field of optical elements, in particular to a manufacturing process of a novel X-ray grating. Background technique [0002] Since the discovery of X-rays by the German physicist Roentgen in 1895, X-ray imaging technology has accompanied mankind for more than a century, and has been used in many fields closely related to human life, such as medicine, biology, material science, industry and safety inspection. Remarkable results have been achieved; for example, the well-known ray computed tomography (CT) in medical imaging, and the X-ray security inspection equipment widely used in subways and airports have played a role in improving people's quality of life and maintaining social security. pivotal role. [0003] The traditional X-ray imaging technology uses the attenuation characteristics of substances to X-rays to image objects, and is often used to detect substances composed of heavy element materials such as met...
