Application of Near Infrared(NIR) Spectroscopy to Wood Science

For realizing the forest definite cultivation and optimal utilization of wood resources, a large and more comprehensive sampling population would be needed to provide the basic information for the effective decision. Near infrared (NIR) spectroscopy is an advanced spectroscopic tool for nondestructive evaluation of wood, and it can quickly, accurately estimate the properties of increment core, solid wood or wood meal. Recently, NIR have applied extensively to estimate wood properties and wood processing and so on. This article introduced the basic principle of NIR and its main application, and then reviewed the application and progress of NIR in the wood properties, wood processing and modification and wood composites. It is optimistic to conclude that NIR is an empirical method for wood science research which will get the extensive application in wood science and technology, and can contribute to the forest definite cultivating, genetic manipulation of trees and optimal utilization of wood.
