摘要：
Based on Huygens-Fresnel diffraction integral, the expression of intensity distribution of the self-reconstruction beam is obtained and used to study the intensity evolution of self-reconstruction beams. It is shown that the intense central spot size of the self-reconstruction beam is larger than that of the non-diffracting beam before focusing. This property limits the application of the self-reconstruction beams.
