Abstract

L'invention concerne un dispositif de rasage laser, comportant: une source laser (1), une unité de mise en forme laser (2), et une surface de rasage (3). La source laser, l'unité de mise en forme laser et la surface de rasage sont disposées successivement. Une fois que la source laser est soumise à une imagerie au moyen de l'unité de mise en forme laser, des points lumineux laser linéaires (7) sont rassemblés au-dessus de la surface de rasage. Des points lumineux laser linéaires sont ajoutés au dispositif de rasage laser sur la base d'un rasoir manuel d'origine. Les poils de barbe (8) sont coupés au niveau d'intersections avec les points lumineux laser linéaires. L'exigence d'acuité d'une lame de rasoir est réduite, la durée de vie d'un rasoir est prolongée, et le risque de coupure dans la peau lors du rasage est évité.
