摘　　要：Self-healing in optics generally refers to the ability to reconstruct itself and restore the original state after encountering obstacles in the propagation of the light field.In this research,we observe the processes of the wave fields from perfect to defect in front of the focal plane of the 4f system,finally returning to an intact situation after the plane.According to simulations and experimental results,there is a minimum self-healing distance for the moirélattice field that positively associates with the radius of the defect[obstacle]in the nondiffracting transmission range.Furthermore,it is observed that the defect self-healing is a process of“repairing the center and then repairing the edges.”These findings can be applied in areas such as optical imaging,capture,and information processing.
