Wood Species Differentiation Technologies

We are seeking for a technology or a combination of technologies to discriminate on line, in real time and in harsh industrial environment different wood species (mostly spruce, pine and fir) whether the wood is in the form of a whole tree-length, a log (barked or unbarked), sawn wood or wood chips, whether the wood is frozen or not.

Thanks for your help.

Regards

Vincent

Vincent,
The upcoming 16th International Nondestructive Testing and Evaluation of Wood Symposium
Beijing, China, May 11-13, 2009, http://www.ndt2009.cn/, is probably a valuable source of information.
My first idea would be a knowledge based visual + IR system. We use LIBS (laser induced breakdown spectroscopy) for concrete type determination (works also for glass or metal sorting). No idea at the moment, if that could help.
Regards, Ernst

We have real-time x-ray based system that can be used for sorting woods depending on its density. The need not have direct with the detector. This may be of your interest.
