This paper will introduce a new application of Optical Coherence Tomography (OCT) to the monitoring of vulnerability
of rock art monuments in-situ. The porosity of the host rock is an important factor affecting the susceptibility of rock art
monuments to decay. Pore characteristics of rocks are one of the main factors that control the intensity of physical
deterioration. OCT has successfully been applied to paintings and archaeological objects, including geological materials,
to produce cross sectional images non-invasively. The stack of cross sectional images can be rendered as a volume to
visualise the structure in depth over an extended area. Preliminary studies show that it can directly image the pores and
subsurface structure to within 500microns of the surface depending on lithology. This study aims to analyse this stack of
cross sectional images computationally to enable the description of the pore space distribution which will be compared
with spatially resolved NMR porosity measurement for the samples.
