| Popis: |
In the previous chapter thermography has been shown to have potential for the identification of defects in adhesive bonds. The current chapter will initially provide an in depth review of the main types of thermography that use the addition of energy from light sources, namely pulsed, lock-in and pulse phase thermography. The types of detectors that may be used for these techniques are then considered. The underpinning physics of heat transfer that enables the detection of defects using thermography are then introduced before interpretation of the thermal data to extract estimated defect size is discussed. The practicalities of experimentation using thermography are then introduced including the experimental setup. Software and data collection and processing methods used in the current work are introduced and the importance of various variables studied. From this investigation knowledge of the importance of the experimental parameters is obtained and used in the remainder of experimental work. |
