Abstract
L’invention concerne un dispositif optique de déviation d’un faisceau lumineux (1) comprenant :- un premier élément réflectif (4) plan, disposé de manière à réfléchir un faisceau lumineux entrant (2) en un faisceau lumineux réfléchi (5), s’étendant dans un premier plan (11), ledit faisceau lumineux entrant et ledit faisceau lumineux réfléchi définissant un plan d’incidence ; et- un deuxième élément réflectif (6) plan, disposé pour réfléchir ledit faisceau lumineux réfléchi en un faisceau lumineux sortant (3), s’étendant dans un deuxième plan (12) transverse au plan d’incidence ;ledit premier plan et ledit deuxième plan étant sécants selon une droite d’intersection (D) et formant entre eux un angle dièdre (BETA), ledit premier élément réflectif et ledit deuxième élément réflectif sont solidairement mobiles en rotation autour d’un axe de rotation (10) sensiblement confondu avec ladite droite d’intersection.
