Abstract
(EN) Systems and methods for scattering or deviating a laser beam are provided. A system utilizing a lenticular sheet and a laser source projecting a laser beam onto the lenticular sheet produces shapes such as laser cones. Minor adjustments of the laser source with respect to the lenticular sheet may vary the size and shape of the laser cone that provides for improved Light Detection and Ranging (LIDAR) systems. A diffraction grating added in the path of the laser beam causes a laser pattern of a matrix of lines to be produced which also provides for improved. Interference between multiple lenticular sheets may be used to deviate a laser beam to protect military assets from laser-guided projectiles and/or laser acquisition.'
(FR) L'invention concerne des systèmes et des procédés pour diffuser ou dévier un faisceau laser. Un système utilisant une feuille lenticulaire et une source laser projetant un faisceau laser sur la feuille lenticulaire produit des formes telles que des cônes laser. Des ajustements mineurs de la source laser par rapport à la feuille lenticulaire peuvent faire varier la taille et la forme du cône laser, ce qui permet d'obtenir des systèmes améliorés de détection et de télémétrie par la lumière (LIDAR de l'anglais "LIght Detection And Ranging"). Un réseau de diffraction ajouté dans le chemin du faisceau laser provoque la production d'un motif laser d'une matrice de lignes qui assure également une amélioration. L'interférence entre de multiples feuilles lenticulaires peut être utilisée pour dévier un faisceau laser pour protéger des atouts militaires contre des projectiles guidés par laser et/ou l'acquisition laser.
