ACCURATE MEASUREMENT OF SPECTRAL REFLECTIVITY OF FLOTATION FROTH BUBBLES
The colour of flotation froth (3) is determined by Illuminating the froth (3), capturing a digital image of the froth (3) in a multispectral light sensor (6), and using specular reflection intensity of an illumination source (1) from gas-liquid interfaces on flotation froth bubbles in the froth (3),...

| description | The colour of flotation froth (3) is determined by Illuminating the froth (3), capturing a digital image of the froth (3) in a multispectral light sensor (6), and using specular reflection intensity of an illumination source (1) from gas-liquid interfaces on flotation froth bubbles in the froth (3), as white reference to calibrate different wavelength bands of the light sensor (6).
La couleur de la mousse de flottation (3) est déterminée par éclairage de la mousse (3), capture d'une image numérique de la mousse (3) dans un capteur de lumière multispectrale (6), et utilisation de l'intensité de réflexion spéculaire d'une source d'éclairage (1) à partir d'interfaces gaz-liquide sur des bulles de mousse de flottation dans la mousse (3), en tant que référence blanche pour étalonner différentes bandes de longueur d'onde du capteur de lumière (6). |
