Session Title: Non-contact Interferometric Surface Metrology

We begin with a review of the theory of operation of interferometers and interference microscopes in particular, using language and visuals accessible to a broad audience. A survey of instruments takes us through automated phase shifting systems and coherence scanning interferometers—presently the most widely used microscope for general-purpose surface profiling on the microscope scale. Armed with this background, we proceed to applications, best practice, data interpretation and presentation, facilitated by hands-on demonstration of a state of the art instrument for 3D surface topography measurement.
