The use of surface imaging for claims support

Imaging is a rather large field – with optical microscopy worthy of an article on its own, but in this article we are going to look at two particular areas of imaging.

Surface topography imaging (including statistical quantification) and surface chemical species mapping in both 2D and 3D.

White light interferometry

White light interferometry (WLI) is a noncontact 3D surface profiling technique utilising white light. It is conducted using a microscope, a white light source and a stage. The difference with the microscope used is that the incident light is diverted from the test surface and half of the incident light is sent to a mirror flat reference plane inside the microscope, and so the incident beam goes to two places before the reflected beams are re-combined to generate an interference pattern. Z-values for every pixel are generated from the difference in distance between the two beams.

The types of data that can be generated include a ‘Pseudo-colour height map’ which is a 2D representation of a 3D surface in which the third dimension determines the colour of every pixel.
