TRANSPARENT OPTICAL COMPONENT HAVING CELLS FILLED WITH AN OPTICAL MATERIAL

摘要

The method involves obtaining a layer structure (4) comprising cells (1). An optical material e.g. powder, is introduced in each cell until average filling levels (h1-h5). Random or pseudo-random variations of the filling levels are introduced between the cells. The variations of the levels between the cells are determined such that phase differences of visible light rays (R1-R5), respectively crossing the cells along a direction (N) perpendicular to a convex surface (S1) of the structure, present root mean square that is fourteen times less than a wavelength of the light.
