Polarization-resolved second-harmonic-generation optical coherence tomography in collagen.
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-harmonic-generation spectroscopy. As a consequence of the coherent detection required for OCT, polarization-resolved images arise naturally. We d...
متن کاملHigh-resolution frequency-domain second-harmonic optical coherence tomography.
We used continuum generated in an 8.5 cm long fiber by a femtosecond Yb fiber laser to improve threefold the axial resolution of frequency domain second-harmonic optical coherence tomography (SH-OCT) to 12 microm. The acquisition time was shortened by more than 2 orders of magnitude compared to the time-domain SH-OCT. The system was applied to image biological tissue of fish scales, pig leg ten...
متن کاملHigh-resolution second-harmonic optical coherence tomography of collagen in rat-tail tendon
A high-resolution second-harmonic optical coherence tomography sSH-OCTd system is demonstrated using a spectrum broadened femtosecond Ti:sapphire laser. An axial resolution of 4.2 mm at the second-harmonic wave center wavelength of 400 nm has been achieved. Because the SH-OCT system uses the second-harmonic generation signals that strongly depend on the orientation, polarization, and local symm...
متن کاملClinical Applications of Optical Coherence Tomography in Ophthalmology
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...
متن کاملExperimental Visualization of Labyrinthine Structure with Optical Coherence Tomography
Introduction:Visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. Optical coherence tomography (OCT) is a high-resolution imaging technology which may be used for the visualization of tissues. In this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.Materials and Methods:Thr...
