Intensity-interferometric spectral-domain optical coherence tomography with dispersion cancellation
We describe a technique for cancelling group-velocity dispersion in spectral-domain (SD) optical coherence tomography (OCT) based on classical intensity correlations. As a classical analogue of quantum OCT, a Hong-Ou-Mandel interferometer is combined with a conventional SD-OCT setup, and correlations between different spectral intensities are calculated.
It is shown theoretically that a simple computational procedure used in SD-OCT enables scanless cross-sectional imaging with both dispersion cancellation and a factor-of-√2 resolution enhancement. The method involves no ultrafast detectors and works with common light sources.
