热中子相衬成像技术的初步探索

Neutron phase contrast imaging technique

介绍了中子相衬成像原理及其特点,对中子相衬成像中的同轴轮廓法进行了重点论述,讨论了相衬成像的条件及实验技术,简介了SPRR-300拟进行的相衬成像技术研究方法。

The principle for neutron phase contrast is presented in this paper. Emphases discuss on in-line neutron imaging principle. The experiment technique and condition of neutron phase contrast imaging are discussed. At last, introduce the research project on SPRR-300 neutron imaging system.
