Abstract

Las presentes enseñanzas incluyen un método para medir un espesor de película completo. El método puede incluir la formación de una película polimérica (10) y la medición del espesor de la película (10) con una cámara (20) que recopila imágenes espaciales y espectrales de una pluralidad de puntos a la vez. La cámara puede recopilar una imagen de línea de una línea de la película. La cámara puede ser una cámara hiperespectral de infrarrojo cercano. Al analizar los datos en bruto recopilados durante la etapa de medición, las franjas de los datos en bruto pueden corregirse mediante el uso de un análisis de mínimos cuadrados clásico.
