摘　　要：开展木材无损检测是提高木材利用率,优化木材资源的重要手段。高光谱成像技术作为一种先进的无损检测技术,能同时获取待测物的光谱与图像信息,具有图谱合一的优点。介绍了高光谱成像技术的原理、装置以及数据处理方法,并首次详细介绍了该技术在木材及木制品的缺陷识别、重要物理力学性质检测以及化学性质预测等方面的研究进展。通过综合分析已有的研究,表明高光谱成像技术在木材及木制品品质无损检测中具有良好的应用前景。Wood nondestructive detection is an important technology to increase wood utilization rate and optimize forest resources. As an advanced nondestructive detection technology, hyperspectral imaging（HSI） integrates conventional imaging and spectroscopy to attain both spatial and spectral information from an object. It has the advantages of non-destructively detecting both physical, morphological characteristics, and chemical information of the object in many fields. This paper introduced the hyperspectral imaging technology, including its principles, equipment, image acquisition, processing methods and etc. Furthermore, recent advances in the application of HSI to wood and wood products quality assessment such as defect identification, physical-mechanical properties detection and constituent analysis were reviewed comprehensively for the first time. The review indicated that HSI had good application prospects in the nondestructive detection of wood and wood products.
