Abstract

The properties of micro-porous ceramics are studied in the present work using a tunable diode-laser-based setup. The relative optical porosity is retrieved by using gas in scattering media absorption spectroscopy (GASMAS) – which yields the path length travelled by photons through the gas-filled pores – and frequency domain photon migration (FDPM) – which evaluates the mean optical path length (MOPL) through the whole ceramic. The relationship between the relative optical porosity and the physical porosity is also studied.
