Accurately tracking the laser beam to the moving target is an important issue in the laser tracking system. In this paper,a new type of self-accelerating beam is designed by using a spatial phase modulator. The beam can be transmitted in a non-straight line along the preset orbit,so that the traditional turntable using for the target tracking can be replaced in a certain range. This kind of beam also has the characteristics of no diffraction,which can improve the laser energy density at the target. In this paper,the technology of the spatial optical modulation is used to realize the transmission of various preset orbits in the experiment,and the characteristics of controllability and no diffraction in the beam transmission are verified,which lays the foundation for the next step of the technology to be applied.
