The Development of Optical Coherence Tomography in Dermatology

Dermatology would appear to be an ideal application for OCT imaging as the skin surface is readily accessible and much of skin pathology occurs within the surface of the skin. Initial attempts to develop skin OCT were frustrated by the higher refractive index of skin in comparison with the eye.[1] This was resolved by a shift from the visible-light wavelengths employed for ophthalmic OCT to infrared wavelengths, which are less attenuated by skin, and all commercially available systems now use the 1300-nm waveband.[9]
