Objective Due to its peculiar phase and intensity distribution, the vortex beam has attracted extensive attention in particle manipulation and communication. Interference of a vortex beam with a plane wave can generate a helix beam with peculiar helical intensity distribution, providing a potential research platform for studying nonlinear topological edge solitons and anomalous topological phases. Multiple vortex and helix beams arrange in a specific distribution to form the field of the optical vortex array (OVA) and optical helix array (OHA). The array has multiple phase singularities compared to a single beam, which has essential applications in multiparticle manipulation and multichannel communication. The wideranging applications of array fields rely on generating highquality optical fields. Currently, various methods have been proposed to generate OVA and OHA, such as using fractional Tabor effect, grating diffraction, or direct adoption of vortex lasers. In these methods, by employing the fractional Talbot effect, the field with the best contrast can only be obtained at a specific distance. The intensity distribution of the OVA generated by grating diffraction is not uniform , and
