Moiré effect in multilayered 3D lattice

The moiré effect was observed in a multilayered three-dimensional (3D) structure with voxels at the points of a simple cubic lattice. Visual corridors result from the moiré effect. The frontal camera’s corridors appear at distinctive angles with rational tangents. We analyzed the effects of distance, size, and thickness. We carried out computer simulation and physical experiments; both confirmed the distinctive angles of the moiré patterns for the three camera locations near the facet, edge, and vertex. The conditions for the moiré patterns to appear in the cubic lattice were formulated. The results can be used in crystallography and in minimization of the moiré effect in LED-based volumetric 3D displays.
