Paper Abstract

Spectral radar is an optical sensor for tomography, working in the Fourier domain, rather than in the time domain. 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. One important property of optical coherence tomography (OCT) sensors is the dynamic range. We will compare the dynamic range of spectral radar with standard OCT. The influence of the Fourier transformation on the dynamic range of spectral radar will be discussed. The clinical relevance of the in vivo measurements will be demonstrated.
