中子相衬层析成像方法

介绍了中子相衬和中子层析的工作原理，提出了中子相衬层析成像方法．这种方法兼备了相衬和层析的各自优点，不采用干涉术，能高分辨率地重构待测样品的三维空间位相分布，能测试和分辨吸收系数非常相近样品的空间结构．

The principle for neutron phase contrast and tomography is presented-in this paper. The imaging method for neutron phase-contrast tomography is suggested. It has the merits of both neutron phase contrast and tomography. The 3D space distribution for phase objects can be reconstructed with high resolution without using interferometry. The objective space structure with near absorption coefficient can be detected and resolved.
