Principles of OCT
Optical Coherence Tomography (OCT) is an advanced imaging technology based on low-coherence optical interferometry. Light from a broadband source is divided into two paths: a sample beam, which illuminates the target and undergoes backscattering within the tissue or material, and a reference beam, which reflectsfrom a fixed reference mirror. The two beams are then recombined to produce aninterference signal.
Interference occurs only when the optical path difference between the sample and reference arms lies within the coherence length of the light source. By analyzing changes in this interference signal as the optical path length varies, OCT extracts depth-resolved structural information. This enables high-resolution cross-sec-tional (2D) and volumetric (3D) imaging of internal microstructures – non-invasively and in real time.
