摘要
This paper explores the use of optical sensors to study the oxygen diffusivity of oak wood staves in wine barrel ageing for four months. 2-D oxygen distribution measurements were performed with planar optodes in combination with a colour RGB camera. The transparency of the optode enables to study the correlation of spatial heterogeneities -due to wood swelling during wetting- in O-2 concentration over the wood surface with data on the different anatomical structures involved. For the first time, oxygen dynamics were described with a resolution that permits the identification of the role of wood anatomy on oxygen permeability/diffusivity.
