Abstract

An optical security component intended to be checked in reflection in a checking spectral band includes a layer that is reflective in the checking spectral band. The layer exhibits a structured zone that includes microstructures distributed spatially in a uniform manner over a whole of the structured zone so as to form an optical structure that is at least partially scattering in the checking spectral band. The microstructures have heights that are distributed according to a random function, modulated over the structured zone by a modulation function so as to form, after illumination of the optical security component at a given angle, an image identifiable by observation in reflection.
