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 ...

Optical Coherence Tomography (OCT): Principle and Technical Realization

High Resolution Imaging in Microscopy and Ophthalmology, 2019
Optical coherence tomography (OCT) is a non-invasive technique for cross-sectional tissue imaging. It typically uses light in the near-infrared spectral range which has a penetration depth of several hundred microns in tissue.

Spectral-Domain OCT Measurements in Alzheimer's Disease: A Systematic Review and Meta-analysis.

Ophthalmology (Rochester, Minn.), 2019
TOPIC OCT is a noninvasive tool to measure specific retinal layers in the eye. The relationship of retinal spectral-domain (SD) OCT measurements with Alzheimer's disease (AD) and mild cognitive impairment (MCI) remains unclear.
