Abstract
An optical device () for forming a distribution of a three-dimensional light field comprises: an array () of unit cells (), a unit cell () being individually addressable for switching the optical property of the unit cell () between a first and a second condition; wherein the unit cells () are configured to be selectively active or inactive and wherein the array () comprises at least a first and a second disjoint subset (), and wherein the unit cells () in a subset () are configured to be jointly switched from inactive to active, wherein the active unit cells () are configured to interact with an incident light beam () for forming the distribution of the three-dimensional light field; and wherein the optical device () is configured to address inactive unit cells () for switching the optical property of unit cells ().
