Abstract
An optical arrangement comprising a plurality of cells arranged in a two-dimensional array on, into, or partly into an optical medium, each said cell having a pattern structure comprising a number of grooves which are parallel to each other and which form a grating. The grating of each cells forms at least two sections which are displaced in relation to each other by a predetermined distance in a direction which is essentially perpendicular to the longitudinal direction of the grooves. The grooves of two or more adjacent cells are unaligned with one another for controlling the phase or amplitude of one or more incident optical waves when the cells receive the incident optical waves.
