A review of the optical properties of biological tissues
TLDR
The known optical properties (absorption, scattering, total attenuation, effective attenuation and/or anisotropy coefficients) of various biological tissues at a variety of wavelengths are reviewed in this article.Abstract:
The known optical properties (absorption, scattering, total attenuation, effective attenuation, and/or anisotropy coefficients) of various biological tissues at a variety of wavelengths are reviewed. The theoretical foundations for most experimental approaches are outlined. Relations between Kubelka-Munk parameters and transport coefficients are listed. The optical properties of aorta, liver, and muscle at 633 nm are discussed in detail. An extensive bibliography is provided. >read more

Photorefractive acousto-optic imaging in thick scattering media at 790 nm with a Sn 2 P 2 S 6 :Te crystal
TL;DR: This work experimentally demonstrates the possibility to perform a self-adaptive wavefront holographic detection at 790nm, within the optical therapeutic window where absorption of biological tissues is minimized, and represents an interesting approach for breast cancer detection.

Quantitative evaluation of scattering in optical coherence tomography skin images using the extended Huygens–Fresnel theorem
Mohammad R. N. Avanaki,Adrian Gh. Podoleanu,John B Schofield,Carole A. Jones,Manu Sira,Yan Liu,Ali Hojjat +6 more
TL;DR: The simplification introduced by the utilization of a dynamic focus OCT system eliminates the need to deconvolve the reflectivity profile with the confocal gate profile, as the sensitivity of the OCT system is constant throughout the axial range.

Measurement of the complex refractive index of tissue-mimicking phantoms and biotissue by extended differential total reflection method
TL;DR: An extended differential total reflection method is introduced to determine the complex refractive index of biotissue and the real part is directly determined by differential of the reflectance curve, and the imaginary part is obtained from nonlinear fitting.

New contributions to the optics of intensely light-scattering materials.
TL;DR: In this paper, the Gurevic and Judd formulas were derived from the Kubelka-Munk differential equations, and they are exact under the same conditions as in this paper, that is, when the material is perfectly dull and when the light, is perfectly diffused or if it is parallel and hits the specimen under an angle of 60° from normal.

Time resolved reflectance and transmittance for the non-invasive measurement of tissue optical properties.
TL;DR: A simple model is developed, based on the diffusion approximation to radiative transfer theory, which yields analytic expressions for the pulse shape in terms of the interaction coefficients of a homogeneous slab.

The delta-Eddington approximation for radiative flux transfer
TL;DR: In this paper, the delta-Eddington approximation was used to calculate monochromatic radiative fluxes in an absorbing-scattering atmosphere, by combining a Dirac delta function and a two-term approximation, which overcomes the poor accuracy of the Eddington approximation for highly asymmetric phase functions.
