Abstract

Appareil d'observation d'une couche (C) à la surface d'un liquide (L), comprenant : - une cuve (CV) destinée à contenir ledit liquide ; - un corps solide (CS) agencé à l'intérieur de ladite cuve ; - un actionneur (ARH), dit de réglage en hauteur, agencé pour contrôler la distance dudit corps solide de la surface dudit liquide selon une direction dite verticale, perpendiculaire à ladite surface ; et - un système optique d'éclairage et d'observation (SO), agencé pour éclairer la surface dudit liquide en correspondance dudit corps solide et pour l'observer en réflexion suivant un axe orienté selon ladite direction verticale ; caractérisé en ce que ledit système optique d'éclairage et d'observation n'est pas adapté pour éclairer la surface dudit liquide en lumière polarisée et l'observer à travers un analyseur de polarisation. Procédé d'observation d'une couche à la surface d'un liquide mettant en œuvre un tel appareil.
