Abstract

There is provided a device for non-destructive detection of internal defects comprising two or more imaging systems selected from the group comprising; a millimetre-wave (MMW) imaging system comprising a millimetre-wave radiation detector (708) configured to detect electromagnetic radiation with a frequency in the millimetre range; a near-infra-red (NIR) imaging system comprising a near-infra-red laser source (not shown) and a near-infra-red radiation detector (706); and a capacitance imaging system comprising two coplanar electrodes separated by an insulating gap, an alternating voltage source and a means for measuring voltage output by one or more electrodes. The figure shows a schematic of a combined MMW and NIR imaging devices. Hybrid focussing optics (702, 704) are configured to simultaneously reflect MMW (710) and NIR (712) radiation onto the respective detectors. The device further comprises a processor configured to analyse data from each of the imaging systems, so as to determine the presence of damage under the surface and further configured to combine image data from each of the two or more imaging systems.
