White light interferometry, or low coherence interferometry, is the basis of OCT. An interferometer with a low coherence, broad bandwidth #lightsource is typically used in the optical setup. The reference and sample arms, respectively, split and recombine light.

Furthermore, a narrowband light source with a central wavelength of around 1000 nm is used in #sweptsourceOCT. A short cavity swept laser can emit multiple light frequencies, which can then be rapidly tuned over a wide bandwidth.

Prior to the introduction of OCT, other imaging methods such as ultrasound waves and MRI were used for imaging. On the other hand, swept source optical coherence tomography uses a slightly different mechanism to perform the same operation. Unlike sound waves or MRI techniques, OCT uses light waves to produce images.
