Abstract
L'invention concerne des dispositifs (100) et des procédés pour mesurer la concentration de fibres dans l'air. Les dispositifs comporte des moyens à écoulement (5 et 6) pour produire un écoulement laminaire sur une partie des fibres (20) d'un échantillon d'air et une source lumineuse (9) pour générer un faisceau lumineux (12) dirigé vers les fibres (20) s'écoulant sous l'effet du flux laminaire de sorte qu'une lumière diffusée soit produite. Ledit dispositif présente aussi un capteur (14) pour capter une partie de cette lumière diffusée et pour produire un signal de sortie à partir duquel une estimation de la concentration de fibres respirables peut être effectuée.
