Abstract

Un dispositivo de medición para la medición sin contacto mecánico de una capa, donde el dispositivo de medición incluye una fuente de luz funcional para generar un pulso adaptado para interactuar con la capa para generar una onda térmica en un medio gaseoso presente adyacente a la capa. La onda térmica provoca que se genere una señal acústica. El dispositivo de medición incluye, además, un detector adaptado para detectar una primera señal sensible a la señal acústica, donde el detector no está en contacto mecánico con la capa. La primera señal es representativa de la capa medida.
