| Optical Coherence Tomography(OCT) |
Optical coherence tomography (OCT) is an interferometric depth-resolved imaging modality. It captures micrometer-resolutioned, three-dimensional images from optical scattering media (e.g., biological tissue). OCT typically utilizes a near-infrared light source. The use of relatively long wavelength light allows it to penetrate deeply into the scattering medium. Depending on the properties of the light source, OCT has achieved sub-micrometer resolution with very wide-spectrum sources emitting over a ~100 nm wavelength range.
A relatively recent implementation of OCT, frequency-domain OCT, provides advantages in signal-to-noise ratio, permitting faster signal acquisition. Commercially available OCT systems are employed in diverse applications, including medical imaging, industrial 3D inspections. Notably, in the ophthalmologic application, it can be used to obtain detailed structural images of the retina. |
