Thermography Analysis for Detecting Defects in Lumber
Introduction The range of wavelength of the infrared, called thermal emission, is 0.79 μm ~1,000 μm. All objects with temperature over 0 Kelvin release energy by infrared ray. The infrared thermography has been used for nondestructive testing. The system detects the infrared radiated from the objects and measures surface temperature of objects. The infrared thermography can get the real time data in noncontact way. IR thermography has been widely used in various areas, such as, application of maintenance of the aircraft, medical application, electronics, and building thermography. However, IR thermography nondestructive test is difficult to apply to detect defects in wood. Because wood is anisotropic, nonhomogeneous and hygroscopic.
