摘　　要：Neutron imaging is an invaluable tool for noninvasive analysis in many fields.However,neutron facilities are expensive and inconvenient to access,while portable sources are not strong enough to form even a static image within an acceptable time frame using traditional neutron imaging.Here we demonstrate a new scheme for single-pixel neutron imaging of real objects,with spatial and spectral resolutions of 100 lm and 0.4%at 1A,respectively.Low illumination down to 1000 neutron counts per frame pattern was achieved.The experimental setup is simple,inexpensive,and especially suitable for low intensity portable sources,which should greatly benefit applications in biology,material science,and industry.在众多科学领域,中子成像是进行无损分析的宝贵工具.但大型强束流中子源的产生设备昂贵且不方便获取,而对于便携式中子源,其强度又不足以在可接受的时间范围内使用传统中子成像方法得到高分辨率的图像.为此,本文提出了一种用于真实物体的单像素中子成像的新方法,其空间分辨率和能谱分辨率分别达到100μm和0.4%(在1A),并实现了每帧图案仅1000中子的低计数.与现有的中子透射成像相比,该方法的装置简单、成本低廉,尤其适用于低强度的便携式中子源,因而在生物学、材料学和工业领域具有非常重大的应用前景.
