Abstract

A method for contactless measurement of the density of a porous material, using a measurement of the refractive index of the material by optical coherence tomography.In the optical coherence tomography technique, the optical path corresponding to the crossing of an object made of the material by a light beam used in the technique, is determined, the thickness of the object is determined, the refractive index of the material is determined from the optical path and from the thickness, and the density of the material is determined from the refractive index.
