{wiki=Spectral_interferometry}
Spectral interferometry is an advanced optical measurement technique that exploits the interference of light waves to extract information about the properties of a sample. It is particularly useful for applications in fields such as telecommunications, material characterization, and biomedical imaging. The basic principle of spectral interferometry involves splitting a light beam into two paths: one that interacts with the sample and another that serves as a reference. These two beams are then recombined, leading to interference patterns that depend on the phase shifts introduced by the sample.
