The generation of a microscale chiral array light field based on Richards‑Wolf vector diffraction theory was realized by introducing a translational phase factor into the incident light. Through simulation research， the flexible regulation of array size and chirality of array subunits was further realized. In addition， the propagation characteristics of the array were explored， and the light field pattern distribution of the chiral array light field was maintained within the ±λ propagation distance. This study greatly enriches the mode of chiral intensity light field， and has good application prospects in the preparation of chiral micro‑nano materials.
