  "abstract": "This study proposes an original methodology for the online measurement of local moisture content (MC) in poplar veneer, combining colour imaging and laser scattering techniques. A database of poplar samples was built, including colour images and a grid of scattering patterns caused by the tracheid eect, acquired in both reection and transmission modes. The analysis shows that colour becomes a discriminant parameter as MC increases. However, colour information alone proved insucient for accurate MC prediction. The model shows limited performance at low moisture contents, with a coecient of determination R² of 0.857 and an absolute error exceeding 100%. In contrast, laser scattering yielded superior results, particularly when using the ellipse area and minor axis as predictors leading to an increase in the coecient of determination above 0.9 and a reduction in absolute error, particularly for sapwood. Both approaches were signicantly inuenced by the wood zone within the log, i.e. whether the veneer originates from sapwood or heartwood. A classication method was therefore developed to discriminate between these two zones. Finally, local MC maps were estimated on samples from two poplar clones (I214 and Dorskamp) using dedicated analytical models. The results are particularly encouraging for green wood.",
