Abstract Optical Coherence Tomography (OCT) yields microscopic cross‐sectional images
of cartilage in real time and at high resolution. As yet, comprehensive grading of …

In this study, we report adaptation of Raman spectroscopy for arthroscopy of joint tissues
using a custom-built fiber-optic probe. Differentiation of healthy and damaged tissue or …

Terahertz-spectroscopy probes dynamics and spectral response of collective vibrational
modes in condensed phase, which can yield insight into composition and topology …

Optical parameters (scattering coefficient s, absorption coefficient k and scattering
anisotropy coefficient g) of hyaline cartilage were studied for the first time. Optical properties …

A new principle for cartilage layer thickness assessments in joints is presented. It is based
on the differences between the absorption spectra of cartilage and subchondral bone …

Mid-infrared spectroscopy (MIR), near-infrared spectroscopy (NIR), and Raman
spectroscopy are all well-established analytical techniques in biomedical applications …

This study investigates the capacity of optical spectroscopy in the visible (VIS) and near-
infrared (NIR) spectral ranges for estimating the biomechanical properties of human …

The feasibility of in vivo measurements in the range of 1000 to 1100 nm and the potential
benefits of operation in that wavelength range for diagnostic applications are investigated …

Recent advances in materials and fabrication techniques provided portable, performant,
sensing optical spectrometers readily operated by user-friendly cabled or wireless systems …

In this study, optical coherence tomography (OCT) with an axial resolution of 15 μm was
used to investigate the depth and degeneration dependences of the refractive index (RI) of …
