AI Technical Summary
Existing neutron imaging systems are bulky and costly, making it difficult to meet the needs of on-site detection and mobile applications. Small neutron sources have low neutron flux, making it difficult to achieve high-resolution imaging. Neutron imaging and gamma element imaging lack a unified coding modulation and synchronous inversion mechanism, resulting in separate structure and element imaging, registration difficulties, and low efficiency.
A neutron-gamma dual-mode synchronous imaging method based on single-pixel detection is adopted. By irradiating the sample with modulated neutron beams of different coding modes and combining neutron transmission and gamma ray information, a forward model and iterative inversion algorithm are established to achieve synchronous acquisition and automatic registration of neutron transmission structure and elemental distribution.
It achieves high-precision simultaneous imaging of structure and elemental information under miniaturized neutron source conditions, solves the problems of discrete imaging and registration difficulties, is suitable for engineering detection, and provides complete information on the internal structure of matter.
