Dispersion-cancelled and dispersion-sensitive quantum optical coherence tomography.
Quantum optical coherence tomography (QOCT) makes use of an entangled twin-photon light source to carry out axial optical sectioning. We have probed the longitudinal structure of a sample comprising multiple surfaces in a dispersion-cancelled manner while simultaneously measuring the group-velocity dispersion of the interstitial media between the reflecting surfaces. The results of the QOCT exp...
متن کاملDemonstration of Dispersion-Cancelled Quantum-Optical Coherence Tomography
We present an experimental demonstration of quantum optical coherence tomography (QOCT). The technique makes use of an entangled twin-photon light source to carry out axial optical sectioning. QOCT is compared to conventional optical coherence tomography (OCT). The immunity of QOCT to dispersion, as well as a factor of two enhancement in resolution, are experimentally demonstrated. PACS numbers...
متن کاملQuantum optical coherence tomography with dispersion cancellation
We propose a new technique, called quantum optical coherence tomography (QOCT), for carrying out tomographic measurements with dispersioncancelled resolution. The technique can also be used to extract the frequencydependent refractive index of the medium. QOCT makes use of a two-photon interferometer in which a swept delay permits a coincidence interferogram to be traced. The technique bears a ...
متن کاملDispersion cancelled low coherence interferometry
Even-order dispersion cancellation, an effect previously identified with frequencyentangled photons, is demonstrated experimentally for the first time with a linear, classical interferometer. A combination of a broad bandwidth laser and a high resolution spectrometer was used to measure the intensity correlations between anti-correlated optical frequencies. Only 14% broadening of the correlatio...
