The theories of diffraction integral and interference are used to analyze the whole process of self-reconstruction of periodic bottle beam which is generated by line-focusing the non-diffracting Bessel beam through an axicon. The intensity distributions along the propagation distance of the periodic bottle beam and the cross-section intensity distribution in different distance after the circle obstacle is simulated numerically; the minimum distance of self-reconstruction is calculated. The results of the proposed work show that after encountering obstacles, the periodic bottle beam will transport around obstructions, transmit along and restore the original characteristics after a distance transmission cycle bottle beam. Optical system is designed to prove the theoretical simulation, the cross-section intensity distribution around a circle or quadrate obstacle can be observed by a microscope and camera system and the experimental results agree well with the theoretical analysis. The results expand the application of the periodic bottle beam.
