WebHow does OCT work? OCT uses light from the red end of the spectrum (near infra-red). As a result, it can penetrate the light-scattering tissues of the eye (and other organs). Transparent tissues, like the cornea and lens of the eye, allow light to pass through. But retina and skin tissue are semi-translucent. This means only some light can ... WebHow Does OCT Work? Optical coherence tomography is based on low-coherence interferometry, using near-infrared light. It uses long wavelength light, allowing it to penetrate deeply into the scattering medium or tissue. The light waves travel to the different areas in the biological material and reflect off, forming a reconstructed profile.
