Optical device for shaping a light beam

Abstract

The invention relates to an optical device (OD) for shaping a light beam, comprising an optical arrangement including a first converging optical element (L1) and a beam splitter (BS). The splitter is configured to receive an incident light beam produced by a source and divide this beam into a plurality of elementary light beams, angularly distributed and directed towards the optical arrangement, the plurality of beams propagating spatially separately at least within a so-called "separation zone". The optical device also includes an optical retarder (OP) located in the separation zone and configured to introduce distinct optical path deviations in the elementary light beams that intercept it.
