Abstract

L’invention concerne un dispositif (100) de localisation d’un objet comprenant : - au moins deux modules d’illumination (10), chaque module d’illumination (10) étant agencé pour émettre un faisceau émis, - au moins un circuit de détection (20) agencé pour recevoir au moins deux faisceaux réfléchis, - une unité de calcul (30) agencée pour déterminer la position dudit objet par analyse desdits au moins deux faisceaux réfléchis, caractérisé en ce que chaque faisceau émis (F) par un desdits au moins deux modules d’illumination (10) présente une distribution lumineuse principale obtenue par combinaison d’au moins deux distributions lumineuses secondaires, ledit dispositif comprenant en outre au moins un composant optique (40) agencé pour occulter une partie desdites au moins deux distributions lumineuses secondaires, une desdites distributions lumineuses secondaires étant agencée pour se superposer au moins en partie à une autre desdites distributions lumineuses secondaires.
