The self-reconstruction of periodic Bottle beam behind obstacle
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 selfreconstructing property and the reconstructed beam maintains the beam intensity distribution.
