Abstract

Se proveen métodos y dispositivos para medir la concentracion de fibras aerotransportadas. Los dispositivos (100) comprenden un medio degeneracion de flujo (5 y 6) laminar para una porcion de las fibras (20) en una muestra de aire, y unafuente lumínica (9) a través de la cual se genera unhaz de luz (12) dirigido hacia estas fibras que fluyen de modo laminar (20) produciéndose la dispersion de dicha luz. El dispositivo además comprende unsensor (14) que detecta una porcion deest a luz dispersa y genera una senal a partir de la cual es posible obtener una estimacion de la concentracionde fibras respirables.
