An OCT system provides two- or three-dimensional images of tissue structure based on optical dispersion, analogous to ultrasound but with light. This system uses laser light of wavelength 1300 nm, has axial resolution of max 5.5 μm, lateral resolution 13 μm, maximum field of view (length×width×depth) 10×10×3.5 mm. The maximum a-scan frequency is 76 kHz.
In clinics, OCT is mainly used in eye and to some extent vascular examinations. However, this system is not adapted for these applications, but instead to examine other tissues such as skin. It can also be used to scan other types of materials else than tissue.
To the right is a picture of the system and pictures taken on the index finger. The structure of the skin layers is clearly visible, as well as the sweat glands.
