Coherence Scanning Interferometry Alchetron The Free Social Encyclopedia Coherence scanning interferometry extends interferometric techniques to surfaces that are complex in terms of roughness, steps, discontinuities, and structure such as transparent films. This chapter considers coherence scanning interferometry which in addition to, or as a substitute for the detection of phase, changes in interference signal strength related to optical coherence.
Figure 1 From Surface Extraction In Coherence Scanning Interferometry 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.

This chapter considers coherence scanning interferometry (csi), which in addition to, or as a substitute for the detection of phase, evaluates changes in interference signal strength related to optical coherence. The capability of optical surface topography measurement methods for measurement of steep and tilted surfaces is investigated through modelling of a coherence scanning interferometer. We present a simulation model of coherence scanning interferometry and confocal microscopy as the two most common techniques for high precision optical surface topography measurement. Coherence scanning interferometry (csi) is a 3d imaging technique for measuring surface topography. the study compares the point spread function (psf) and transfer function (tf) for different imaging methods. Coherence scanning interferometry extends interferometric techniques to surfaces that are complex in terms of roughness, steps, discontinuities, and structure such as transparent films.
