IC Tomography and Infrared Tomography Techniques to Monitor Defect Sites in Palm Tree Trunks
Abstract:
The sonic tomography and infrared thermograph techniques are incorporated to monitor the orientation and the size of the defect sites in the palm tree trunks. The tests are carried out for various conditions of the palm tree trunks, which have the large defect sites caused by the insects. The sonic tomography technique relies on the measurement of the relative sound wave speed by the detectors when the palm tree trunk is excited through the external forces. This technique enables to separate and quantify the damage and the intact volumes. It is found that sonic tomography can be used to identify the damage sites within a reasonable accuracy. The images obtained from the infrared thermograph technique provide information on the presence of the defect sites with the limited capacity for the location and the size of the defect sites in the palm tree trunk.
