Problems solved by technology

However, in the prior art, it is prepared by the pulling method, which is complicated in operation and high in cost.
In the prior art, optical glue is required when using photonic crystals to prepare crystal modules, which will lead to defects such as large gap width, low output efficiency, and low image reconstruction quality, and will also increase the cost of the radiation imaging system composed of photonic crystals.

Abstract

The invention relates to the field of electronic information, in particular to an intelligent fixed photonic crystal manufacturing method and a radiation imaging system. The photonic crystal is prepared through an oil bath heating method, then the crystal A and the crystal B are obtained through cutting and polishing, and the crystal A and the crystal B can be firmly and seamlessly formed into a square crystal array without glue after being assembled according to a certain sequence on the basis of a mortise and tenon joint structure. The invention further provides a radiation imaging system. The radiation imaging system comprises a moving bed module, a photonic crystal module, a photoelectric conversion module and a signal acquisition module. According to the system, the use of optical glue and adhesives is avoided in the square crystal array used in the photonic crystal module for absorbing the high-energy particles, the cost and the complexity of the system are reduced, meanwhile, the moving bed module in the system is loaded with small animals to be subjected to radiation imaging scanning, and the bodies of the small animals can be effectively and manually moved in the image cabin.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to an intelligent fixed photonic crystal preparation method and a radiation imaging system. Background technique [0002] The application principle of the radiation imaging detector is to detect and image various changes such as ionization effects, luminescence phenomena or chemical reactions caused by nuclear radiation in gases, liquids and even solids. So far, there are many types of nuclear radiation detectors used in the world, and their working principles also have certain differences. The medical development of today's nuclear radiation detectors tends to be consistent with the development of nuclear detection technology, and they have all experienced the development of detection, counting and imaging, such as PET. [0003] Photonic crystals are an integral part of the aforementioned radiation imaging detectors. At present, perovskite materials have become a new type of...
