Maximum and minimum amplitudes of the moiré patterns in one- and two-dimensional binary gratings in relation to the opening ratio

The amplitude of the moiré patterns is estimated in relation to the opening ratio in line gratings and square grids. The theory is developed; the experimental measurements are performed. The minimum and the maximum of the amplitude are found. There is a good agreement between the theoretical and experimental data. This is additionally confirmed by the visual observation. The results can be applied to the image quality improvement in autostereoscopic 3D displays, to the measurements, and to the moiré displays.
