Determination of scattering coefficient and scattering anisotropy factor of tissue-mimicking phantoms using line-field confocal optical coherence tomography (LC-OCT)

Journal of the European Optical Society-Rapid Publications, 2023
Line-field Confocal Optical Coherence Tomography (LC-OCT) is an imaging modality based on a combination of time-domain optical coherence tomography and reflectance confocal microscopy.

Role of scattering-factor anisotropy in electron, positron, and photon holography [PDF]

Physical Review B, 1998
We have studied the angular anisotropy in the scattering factor of electrons, positrons, and photons in solids. We show that as a function of angle, the maximum number of dips in the scattering factor{close_quote}s magnitude and jumps of near {pi} in its phase are related to the angular momenta of the bound and resonance states of the potential.

Simultaneous reconstruction of absorption, scattering and anisotropy factor distributions in quantitative photoacoustic tomography [PDF]

Biomedical Physics & Engineering Express, 2020
We present for the first time the simultaneous reconstruction of three optical parameters distributions of biological tissues namely, the absorption μ a and scattering μ s coefficients, as well as the anisotropy factor g of the Henyey-Greenstein phase function as a new optical contrast.

Local scattering anisotropy of the skin as a possible factor of fluorescence borders distortion of neoplasms

Biomedical Photonics
The use of protoporphyrin IX fluorescence imaging in skin tumors is limited by the complexity of light propagation in tissues. A non-invasive scat- tering anisotropy test (comparison of the fluorescence pattern of a tumor with that of a point source ...
