Coherence Scanning Interferometry and White Light Fiber End Interferometers
The visibility of interference fringes related to optical coherence in interferometric microscopes provides a powerful non-contact sensing mechanism for 3D measurement and surface characterization. Coherence Scanning Interferometry (CSI) extends interferometric measurement techniques to complex surfaces in terms of roughness, steps, discontinuities, and structures (such as transparent films). Other benefits include automatic focusing at every point … Read more
