From: Controllable beam reshaping by mixing square-shaped and hexagonal optical vortex lattices
Additional structuring of the far field intensity profiles of mixed square-shaped and hexagonal OV lattices by adding an OV with an opposite TC (a1–a3) (effectively - by removing it), by changing the order of the generation of the respective OV lattices on the SLMs (b1–b3), and by adding a 1-D dark beam (c1–c3). First column of frames - experimental intensity profiles, second column - recorded interferograms. The lattice node spacings as encoded on the SLMs are Δsq = 151 pix. and Δhex = 61 pix. for the square-shaped and for the hexagonal OV lattices, respectively (Δ = 2.48). For the numerical data (last column showing some 10% of the total computational area) again Δ = 2.48, however Δsq = 101 pix. and Δhex = 41 pix.
