Coherence tomography with the ''Spectral Radar'' - Fast optical analysis in volume scatterers by short coherence interferometry

We present a sensor far acquisition of cross-sectional images of volume scatterers (e.g. biological tissue), we call it ''spectral radar''. Medical and technical applications are possible. The sensor is a modified Michelson-interferometer, with a broad bandwidth light source. The scattering amplitude a(z) along one vertical axis from the surface into the bulk can be measured with-in one exposure. No reference arm scanning is necessary. Measurement results of stationary and non stationary scattering phantoms, human skin and of a fish eye in vitro are shown.
