A/ In a first procedure, a 5×5 DOE generated spot pattern with a low inter-spot separation, p = 0.9 µm, was translated with a long step distance, D = 4.4 µm, to generate the expected 900 voxel structure array by 36 successive translations and exposures (6×6 periodic square motif), with an overall fabrication time of 22.5 s.
