We have proposed and experimentally demonstrated that picosecond time-resolved optical spectroscopy in the visible/near-infrared (NIR) region (700-1040 nm) is a useful technique for noninvasive characterization of wood. This technique has been demonstrated on both softwood and hardwood samples treated in different ways simulating the aging process suffered by waterlogged woods. In all the cases, alterations of absorption and scattering spectra were observed, revealing changes of chemical and structural composition.
我们已经提出并通过实验证明，可见/近红外（NIR）区域（700 - 1040 nm）的皮秒时间分辨光谱技术是一种用于木材非侵入性表征的有用技术。该技术已在以不同方式处理的软木和硬木样品上得到验证，这些处理方式模拟了浸水木材所经历的老化过程。在所有情况下，均观察到吸收光谱和散射光谱的变化，揭示了化学和结构组成的变化。
