Optical coherence tomography by spectral radar for the analysis of human skin

The 'spectral radar' is an optical sensor for the acquisition of skin morphology. The scattering amplitude a(z) along one vertical axis from the surface into the bulk can be measured within one exposure. No reference arm scanning is necessary. We discus the theory of the sensor, including the dynamical range and we show in vivo measurements of human skin by a fiber optical implementation of the sensor.
