Based on the equation of the movement of the photoelectrons in the parabola coordinates,the trajectory and movement characteristic of the photoelectrons are analyzed for the various cases. The radiuses of the photoelectrons projecting onto the detector are investigated for the photoelectrons taking various kinetic energies. The results show that the fast photoelectron imaging pattern shows the energy feature of the photoelectrons,as well as the information of the space distribution of the photoelectron orbital. The slowing photoelectron imaging pattern is correlative with the energy of the photoelectron,and the photoelectrons focus mostly on the center of the photoelectron imaging pattern.
