Abstract: The experiment result of Hα radiated photos taken by CCD camera is described in HL 1M device. The photo of various ablation cloud, pellet speed and trajectory are obtained. Through the photo treatment,the space distribution of the radiation is given. The track bending and the appearance of striation are analyzed, inquiring into the physical mechanism of pellet-plasma interactions. Therefore this paper lays the foundation of further measurement for local magnetic field and current profile of plasma with CCD camera under the condition of pellet injection
