Abstract
In some situations, the beam is partially blocked by an obstacle during propagation, and the influence of the obstacle and ways to decrease the influence have been studied for practical applications. The self-healing effect of Bessel beams is considered as one potential technology for this. The optical pin beam (OPB) can evolve into a Bessel-like beam and can retain its robust property after long-distance propagation. In this paper, we study the propagation property of an OPB after it is partially blocked by an obstacle. We observe the self-healing effects of the OPB and find that it exhibits robust self-healing abilities. An experiment is conducted to confirm the self-healing effect of the OPB. As one example of the application of the self-healing effect, the radiation forces of an obstructed OPB are calculated. Our findings may have important applications in various fields such as micro-imaging, trapping, and long-distance optical communication under disturbance conditions.
