Abstract: A method of monitoring the surface of a sample under test is provided and the method comprises the steps of:
illuminating the surface with light (20) polarised in a first direction;
viewing light reflected from the surface through a polarising filter (27) arranged at 90° to the first direction,
wherein the surface of the sample under test is provided with a marked area where diffuse reflection of the incident polarised light will occur in order to improve the contrast between the marked area and the surface of the sample under text.
