Optical Coherence Tomography

Optical Coherence Tomography (OCT)

An Optical Coherence Tomography (OCT) system uses low coherence interference to measure reflectance versus distance into a material. Light from a semi-broadband source (like a Superluminescent LED) is split into a reference arm (with a fixed mirror) and a sample arm (towards the material to be scanned). The reflected beams from the reference and sample arms are recombined and input to a spectrometer that records the interference pattern vs. wavelength. The periodicity of fringes in the interference pattern is directly related to the depth into the sample material through the Fourier Transform.

Ibsen offers the EAGLE OCT-S spectrometer which is very well-suited for SD-OCT
