From: Controllable beam reshaping by mixing square-shaped and hexagonal optical vortex lattices
Numerical simulations (a–d) and experimental results (e–g). A hexagonal OV array with a lattice constant of 61 pix. is encoded on SLM1 and a square-shaped OV lattice with lattice node spacing of 151 pix. on SLM2. Intensity distribution just behind SLM2 (a) and in front of the focusing lens L (b). Calculated far-field intensity distribution (c) and its respective phase profile (d). Experimentally recorded intensity distributions (e,g), interference pattern (f) and retrieved phase profiles (graph) of the bright peaks denoted in frame (g) of the mixed lattices for the same ratio between their lattice constants. Dashed rhombs - small-scale structures discussed in the text.
