Microwave-induced thermoacoustic imaging of wood: a first demonstration
2019
Zhang, Dan | He, Hang | Zong, Chujing | Liu, Yunfei
Hollow decay is the main problem that affects healthy tree growth and significantly reduces the subsequent practical value of wood. In this work, for the first time, an effective microwave-induced thermoacoustic imaging technology adopted for wood specimens is proposed. The thermoacoustic principle combines microwaves and ultrasonic waves and relies on the microwave penetrating ability and high spatial resolution to generate an ultrasonic excitation source from wood. Thermal ultrasonic imaging technology and high imaging precision present the detection results rapidly, allowing quick, effective, and easy evaluation. This also is the first demonstration of wood microwave-induced thermoacoustic imaging.
