Modeling Of Coherence Scanning Interferometry Using Classical Fourier Coherence scanning interferometry (csi) is any of a class of optical surface measurement methods wherein the localization of interference fringes during a scan of optical path length provides a means to determine surface characteristics such as topography, transparent film structure, and optical properties. Coherence scanning interferometry extends interferometric techniques to surfaces that are complex in terms of roughness, steps, discontinuities, and structure such as transparent films.
Modeling Of Coherence Scanning Interferometry Using Classical Fourier Csi refers to a class of optical surface measurement methods wherein the localization of interference fringes during a scan of optical path length provides a means to determine surface characteristics such as topography, transparent film structure, and optical properties. Coherence scanning interferometry extends interferometric techniques to surfaces that are complex in terms of roughness, steps, discontinuities, and structure such as transparent films. The short coherence length of white light causes the focus depth over which interference occurs to be quite shallow this enables csi to examine rough and discontinuous surfaces just as easily as smooth ones. Here, we present fourier ptychographic coherence scanning interferometry (fp csi), the first transmissive csi modality that integrates the aperture synthesis strategy of fourier ptychographic.

Coherence scanning interferometry is a measurement method based on the acquisition of an image sequence of interference patterns resulting from the superposition of the light coming back from the sample and the light reflected from a reference mirror (fig. 2 (a)). The characterization of imaging methods as three dimensional (3d) linear filtering operations provides a useful way to compare the 3d performance of optical surface topography measuring instruments, such as coherence scanning interferometry, confocal and structured light microscopy. Coherence scanning interferometry (csi), also referred to as white light interferometry (wli), and confocal microscopy (cm) are two of the most frequently used optical profiling techniques due to their outstanding axial resolution and diffraction limited lateral resolution. Coherence scanning interferometry csi uses white light to scan the surface height of smooth to moderately rough surfaces, achieving 1 nm height resolution at any magnification.
