The self-reconstruction of periodic Bottle beam behind obstacle

摘要: 本文分析了由两束贝塞尔（Bessel）光相干产生的周期性局域空心光束（Bottlebeam）遇到障碍物后的自重建特性．由汉克尔波理论分析了自重建的原理，利用衍射积分理论数值模拟了轴上圆形障碍物对光束传输的影响．结果表明，周期性Bottlebeam遇到障碍物遮挡时具有自重建特性，重建后的光束依然保持着障碍物前的光强分布特性．研究结果对于利用周期性Bottlebeam实现微粒的多层面操控具有特殊意义．

Abstract: In this paper, the self-reconstructing property of periodic bottle beam generated by the Bessel beam interfering behind obstacle is analyzed. Based on the Hankel wave theory, we analyze the principle of self-reconstruction. According to the diffraction theory, we derive the evolution of beam behind an on-axis circular obstacle. The results show that the periodic bottle beam has the self- reconstructing property and the reconstructed beam maintains the beam intensity distribution. The research results are significant for realizing the multi-plane micro-manipulation by using a periodic bottle beam.
