Coherence Scanning Interferometry Csi Technology Csi uses either fringe localization alone or in combination with interference fringe phase, depending on the surface type, desired surface topography repeatability and software capabilities. Coherence scanning interferometry (csi), also known as white light interferometry or vertical scanning interferometry, is a non contact optical metrology technique used to measure 3d surface topography.
Pdf Coherence Scanning Interferometry For Additive Manufacture Coherence scanning interferometry (csi) is a widely used topography measurement technique that offers sub nanometer axial resolution and diffraction limited lateral resolution [1, 2]. 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. Csi is able to use additional signal processing to measure in the presence of transparent optical films that confound other measurement methods. these advantages combine to provide exceptional application versatility as the same instrument can be used for a wide range of applications. Coherence scanning interferometry (csi, a type of white light interferometer), is a highly effective technique for measuring surface roughness, owing to its non contact nature, data clarity, high precision, and ability to capture both smooth and rough surface textures.

The csi system is used as an imaging fourier transform spectrometer meaning that the characterizations are achieved by analyzing the interference signal in the spectral domain. Here, we present fourier ptychographic coherence scanning interferometry (fp csi), the first transmissive csi modality that integrates the aperture synthesis strategy of fourier. Coherence scanning interferometry (csi), also known as white light interferometry, has emerged as one of the most powerful, non contact techniques for surface roughness measurement, delivering unprecedented resolution, accuracy, and versatility. The term "csi" was adopted by the international organization for standardization (iso). [2] the technique encompasses but is not limited to instruments that use spectrally broadband, visible sources (white light) to achieve interference fringe localization.
