Abstract

La présente invention concerne un procédé économique permettant de chasser, en les effrayant, des animaux et des oiseaux sauvages (A) nuisibles par rayonnement d'une multitude de faisceaux laser. Selon le procédé décrit dans cette invention, les faisceaux frappent les rétines des yeux des volatiles, les soumettant ainsi à la luminance extrêmement intense du faisceau laser, les effets ultérieurs de ce procédé étant perpétuels sur ces animaux. Le procédé consiste à faire converger le rayonnement d'un ensemble de faisceaux laser (Ln) par rapport à un espace dans lequel on doit empêcher l'invasion des volatiles, afin de former un filet de faisceaux laser (Ln) dans cet espace, de manière à garantir que n'importe lequel de ces faisceaux laser frappe directement les animaux nuisibles (A) dans les rétines, et les soumettre ainsi à la luminance extrêmement intense du faisceau laser. Le procédé décrit dans cette invention permet d'empêcher que ces volatiles ne s'habituent au piège, comme c'était le cas dans l'état de la technique; d'autre part, le filet de faisceaux laser étant activé pendant un certain temps, les volatiles assimilent l'obstacle de lumière intense auquel ils sont confrontés lorsqu'ils tentent de pénétrer dans ledit espace, même lorsque le rayonnement de faisceaux laser est arrêté pendant une période prolongée.
