Angular-spectrum-based analysis on the self-healing effect of Laguerre-Gaussian beams after an obstacle
Jian-Dong Zhang, Zi-Jing Zhang, Jun-Yan Hu +4
Self-healing, as an exotic effect, has showed many potential applications. In this paper, we focus on the self-healing effect of Laguerre-Gaussian beams after an obstacle. By takin…
