Infrared is a part of electromagnetic spectrum not visible for the human eye, but contain important information regarding material status. Several scientific methods have been developed during years to acquire, analyse and interpret the infrared radiation in active and passive way. The technology become especially interesting nowadays when infrared measuring instruments become portable and affordable, being reasonably accurate at the same time. This research summarizes some possibilities of

Near-and mid-infrared spectroscopies as well as hyperspectral and thermal imaging in different configurations are briefly described with a special focus on the specific application in assessment of timber structures. Advantages for implementation but also limiting factors for each technology are listed and discussed.
