Analysis of the application status of terahertz technology in forestry

The frequency of Terahertz (THz) band is between microwave and infrared radiation. THz technology is widely used in non-contact nondestructive testing, material evaluation, security anti-terrorism, medical imaging and diagnosis, communications and other fields. Similarly, THz technology has been widely used in forestry. This paper analyzes the application progress of THz technology in forestry based on the research and application achievements of THz technology in recent years, such as tree species recognition, non-destructive detection of hidden defects in wood, wood moisture content measurement, wood density, some other important application areas (such as dendrochronology, crystalline structure, fiber structure) and summarizes the existing limitations and shortcomings. On this basis, the future application prospect and development trend of THz spectroscopy and imaging technology in forestry are projected. It is expected that this paper can play a positive role in promoting the application of THz technology in forestry, and provide new solutions and methods to solve the technical problems related to forestry.
