Beschreibung
Zusammenfassung:	The invention relates to a method of encoding a set of data on an information carrier comprising data areas each intended to store a data, each data area being characterized by a transmission coefficient and a phase-shift coefficient, said method comprising a step of calculating the transmission coefficient and phase-shift coefficient of said data areas so that an output light pattern corresponding to the intensity pattern of said set of data is generated at a given distance from the information carrier, via interference between light outputted by said data areas in response of an array of light spots periodically applied to non-adjacent data areas.
