The thin piece of scintillatormaterial acts as a neutron-to-light converter. The optical system images light from the scintillator surface to camera for recording.
其中闪烁体将中子信号转换为可见光信号，光学系统则将闪烁体的发光信号成像在条纹相机上进行记录。

The present status of Nal to scintillator matching with other detectors is briefly described in this paper. It's principle, structure mode, material selection and application are also presented.
Adjacent scintillator elements are separated by gaps filled with a composition of white diffuse reflective material, a light absorber, and a castable polymer.
