12Optical Fiber‐Based Optical Coherence Tomography
12.1 Optical Fiber Coherence Tomography Theory
Optical coherence tomography (OCT) has evolved to become a major optical imaging modality in biomedical optics and medicine. OCT performs high‐resolution, cross‐sectional, and three‐dimensional (3D) volumetric imaging of the internal microstructure in biological tissues by measuring echoes of backscattered light [1]. Tissue pathology can be imaged in situ and in real time with resolutions of 1–15 mm, which is 1–2 orders of magnitude finer than conventional ultrasound. The unique features of OCT make it a powerful imaging modality with applications' spanning of many multiple clinical specialties as well as fundamental scientific and biological ...
