Developing a non-destructive portable wood quality inspection system with ultra-compact X-ray source and evaluating the wood qualityof standing tree with it.

利用铃木博士研制的超小型X射线源，对便携式木材质量无损检测系统进行了开发研究。我们发现，使用超小型X射线源可以区分边材和心材、早材和晚材、节区和无节区、虫孔区和正常木材、湿心材和非湿心材。我们继续开发更轻、更紧凑的X射线源，适用于森林中的直立树，并检查计算机断层成像。最后，我们根据多次实验的结果设计了一套检测系统。

Developing research on a non-destructive portable wood quality inspection system with the ultra-compact X-ray source developed by Dr. Suzuki was conducted. We found that it is possible to discriminate between sapwood and heartwood, between earlywood and latewood, between knots area and knots free area, between worm hole area and normal wood, and between wet heartwood and non-wet heartwood, by using the ultra-compact X-ray source. We continued to develop the lighter and more compact X-ray source suitable for use with standing tree in forest, and also to examine computed tomography imaging. We finally designed an inspection system based on the results from several experiments.
