Description
Summary:The use of Makyoh (magic-mirror) topography (MT), an optical surface characterisation tool, is demonstrated in the research of artificial biomineralisation. The method is based on the defocused detection of the whole-sample reflection of collimated light. The sample surface morphology is revealed in the form of dark/bright contrast regions in the reflected image, due to the focusing/defocusing action of the morphological features of the surface. It is shown that MT can be used for the quick, qualitative assessment of the mm and sub-mm scale morphology of the substrates used for deposition of hydroxyapatite layers. In particular, we show the roughening effect in stainless steel substrates due to Ca+P implantation.
