Second harmonic optical coherence tomography [PDF]
Optics Letters, 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

Optical coherence tomography angiography
Kerala Journal of Ophthalmology, 2016 Optical coherence tomography angiography (OCTA) is a non-invasive angiography type without a contrast agent, which provides a detailed assessment of the retinal and choroidal vasculature and visualization of blood flow by detecting motions of ...

Optical Coherence Tomography Angiography
Case Reports in Ophthalmological Medicine, 2018 Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that obtained with older forms of imaging.

Ptychographic optical coherence tomography [PDF]
Optics Letters, 2021 Ptychography is a robust computational imaging technique that can reconstruct complex light fields beyond conventional hardware limits. However, for many wide-field computational imaging techniques, including ptychography, depth sectioning remains a challenge.

Optical Coherence Tomography [PDF]
Science, 1991 A technique called optical coherence tomography (OCT) has been developed for noninvasive cross-sectional imaging in biological systems. OCT uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way that is analogous to ultrasonic pulse-echo imaging.

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 ...

Polarization-resolved second-harmonic-generation optical coherence tomography in collagen [PDF]
, 2004 We describe a novel imaging technique, second-harmonic-generation optical coherence tomography (SHOCT). This technique combines the spatial resolution and depth penetration of optical coherence tomography (OCT) with the molecular sensitivity of second ...
