Abstract:

With the rapid progress of figure and computer technique, there are some new development in non-destructive testing(NDT) technique and equipment of ultrasonic tomography, stress wave tomography, resistance photography, ground penetrating radar and X radial. This paper reviewed the application of NDT method to the evaluation of decay of standing trees, and the testing equipment currently used in NDT of trees and logs. The study may provide reference for the application of NDT technology to the evaluation of the decay of standing trees.

Key words: stranding tree, decay, nondestructive testing, imaging technique
