Anti-erosion plate disbonds and impacts in a composite helicopter rotor blade have been profiled using a number of identical eddy current sensors. The technique is inherently accurate and reproducible. To enable the visualization of suface topography, the analogue signals from the sensors have been integrated using computer software to create 2.D plots, contour maps and 3-D images of the inspected surface. Analogue signals are converted into a colour-coded probability map to facilitate disbond characterisation and image interpretation for in-service inspection. The x,y,z co-ordinates at any point of the inspected surface can be read directly by a screen cursor. A predetermined threshold is applied to display a defect on a background of a different colour. Image quality is such that an untrained operator can locate and measure the 3-D geometry of a defect with precision. The technique has been applied to the detection and visualisation of surface damage on carbon fibre rotor blades. The potential for dynamic visualisation is under investigation.
