White Light Interferometry

Summary

Creating 3D-maps of reflective surfaces using The topography measurement is based on a technique called How do you measure the geometry of micro-optical components, as normal microscopy doesn't work? The answer is WLI finest hour: A scan sequence through a small drop of glue. The setup is a microscopic Michelson Most precise ruler ever built This animation illustrates how the twin observatories of LIGO work. One observatory is in Hanford, ... This instrument uses a physical phenomenon with which we are all familiar---interference of How does a 3D Optical Profilometer measure surface roughness with nanometer precision? In this video, we introduce the Rtec ... Just foolin around on a weekend A look at how to set up and align a ZYGO's Peter de Groot discusses fundamentals and challenges of surface topography measurements using Two (apparently) flat silver mirrors.
