摘要:

A non destructive method for surface strain measurements is proposed to quantify the wood drying quality during convective drying. This method uses a visible laser scan micrometer intercepting needles maintained vertical at the board surface with a special device, and then gives shrinkage values at several surface points. The results analysis is related to heal and mass transfer phenomena.
