  We demonstrate experimentally ghost optical coherence tomography using a
broadband incoherent supercontinuum light source with shot-to-shot random
spectral fluctuations. The technique is based on ghost imaging in the spectral
domain where the object is the spectral interference pattern generated from an
optical coherence tomography interferometer in which a physical sample is
placed. The image of the sample is obtained from the Fourier transform of the
correlation between the spectrally-resolved intensity fluctuations of the
supercontinuum and the integrated signal measured at the output of the
interferometer. The results are in excellent agreement with measurements
obtained from a conventional optical coherence tomography system.
