Numerical simulations (a–d) and experimental results (e–g). Square-shaped OV array with a lattice constant 41 pix. is encoded on SLM1. Hexagonal OV lattice with lattice node spacing of 101 pix. is encoded 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) for the mixed lattices for the same ratio between their lattice constants. Dashed triangle - small-scale structure discussed in the text.
