Abstract
A simple 7 by 7 matrix fibre optic array has been used to illuminate the surface of samples in a raster scan. By mounting the samples on a transducer the system produces an X-Y photothermal scan. Samples with sub-surface features have been scanned and with the use of a graphics software package the images have reproduced the underlying thermal discontinuities in the samples.
