Agarwood is a kind of important and precious traditional Chinese medicine. With the decreasing of natural agarwood, artificial cultivation has become more and more important in recent years. Quantifying the formation of agarwood is an essential work which could provide information for guiding cultivation and controlling quality. But people only can judge the amount of agarwood qualitatively by experience before. Fluorescence multispectral imaging method is presented to measure the agarwood quantitatively in this paper. A spectral cube from 450 nm to 800 nm was captured under the 365 nm excitation sources. The nonagarwood, agarwood, and rotten wood in the same sample were distinguished based on analyzing the spectral cube. Then the area ratio of agarwood to the whole sample was worked out, which is the quantitative information of agarwood area percentage. To our knowledge, this is the first time that the formation of agarwood was quantified accurately and nondestructively.
沉香是一种重要且珍贵的传统中药。随着天然沉香数量的减少，近年来人工种植变得越来越重要。量化沉香的形成是一项至关重要的工作，可为指导种植和控制质量提供信息。但此前人们只能凭经验对沉香的数量进行定性判断。本文提出采用荧光多光谱成像方法对沉香进行定量测量。在365nm激发光源下采集了450nm至800nm的光谱立方体。通过对光谱立方体进行分析，区分了同一样本中的非沉香、沉香和腐朽木材。然后计算出沉香占整个样本的面积比，即沉香面积百分比的定量信息。据我们所知，这是首次对沉香的形成进行准确且无损的量化。
