Dynamical behaviors of optical beams including fundamental and multi-polar solitons in barrier-type nonlocal nonlinear system are presented. Under the influence of barrier-type nonlocality,fundamental soliton experiences periodic oscillations,and its period and degree of oscillation can be effectively controlled by adjusting the parameters of barrier-type nonlocal system. However,for multi-polar soliton,it splits into a corresponding number of fundamental solitons due to suffering from a barrier-type nonlocality; and,these fundamental solitons periodically collide each other during their propagation; their dynamical behaviors can also be controlled by adjusting the parameters of barrier-type nonlocal system.
