Spatial and temporal coherence effects in interference microscopy and full-field optical coherence tomography
Low-coherence optical microscopy or optical coherence microscopy uses light with short coherence length. The well-known case is: “white-light interferometry”, which became recently more known as: “optical coherence tomography”. However, when lenses and microscope objectives are used to create interferometric images, in what is known classically as “interference microscopy” or today as “full-field optical coherence tomography” the spatial coherence starts to play a critical role. In this article the coherence effects in low-coherence optical microscopy are reviewed. As this technology is becoming increasingly publicized due to its importance in three-dimensional imaging, particularly of scattering biological media and optical metrology, the understanding ...
