Abstract

The disclosed subject matter relates to methods for monitoring or controlling a manufacturing process of a material by determining when a variation in surface characteristics takes place. Such surface characteristics correlates to the processing condition of the material and can include density, roughness, porosity, or planarity on a surface of the material. The methods can include herein can include directing a solvent or energy on a surface of the material to form an at least partially modified surface, directing light at an incident angle with respect to the at least partially modified surface, measuring one or more predetermined properties of light reflected from the at least partially modified surface, determining that the material is fully processed based on the measured predetermined property of the light reflected, and optionally adjusting a processing parameter of the manufacturing process in response to the measured predetermined property.
