Experimental Demonstration of Spectral Intensity Optical Coherence Tomography [PDF]
, 2015 We demonstrate experimentally quantum-inspired, spectral-domain intensity optical coherence tomography. We show that the technique allows for both axial resolution improvement and dispersion cancellation compared to conventional optical coherence ...

Phase-dispersion optical tomography [PDF]
, 2001 We report on phase-dispersion optical tomography, a new imaging technique based on phase measurements using low-coherence interferometry. The technique simultaneously probes the target with fundamental and second-harmonic light and interferometrically ...

Optical coherence tomography in pediatric patients: a clinical review
Therapeutic Advances in Ophthalmology, 2020 Optical coherence tomography has improved the ophthalmic clinical examination due to its ability to more accurately characterize pathology of the eye. Optical coherence tomography is now an integral imaging modality for many adult diseases of the retina ...

Phase-conjugate optical coherence tomography [PDF]
, 2006 Quantum optical coherence tomography (Q-OCT) offers a factor-of-two improvement in axial resolution and the advantage of even-order dispersion cancellation when it is compared to conventional OCT (C-OCT).

Second harmonic optical coherence tomography [PDF]
, 2004 Second harmonic optical coherence tomography, which uses coherence gating of second-order nonlinear optical response of biological tissues for imaging, is described and demonstrated. Femtosecond laser pulses were used to excite second harmonic waves from
