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

Error assessment of a wavelength tunable frequency domain system for noninvasive tissue spectroscopy
TL;DR: The biomedical utility of the system is illustrated by noninvasive measurement of the uptake of an intravenously injected dye in rabbit leg Muscle by calculation of the influence of instrumental noise, tissue optical properties, and modulation frequency.

Systems and methods for generating data based on one or more spectrally-encoded endoscopy techniques
TL;DR: In this paper, it was shown that it is possible to generate data associated with at least one portion of a sample using at least a first arrangement of the first arrangement and a second arrangement consisting of a spectrometer arrangement.

Sized-fiber reflectometry for measuring local optical properties
T.P. Moffitt,S.A. Prahl +1 more
TL;DR: In this article, the authors describe a device and method for measuring absorption and reduced scattering properties of tissue using optical fibers with different diameters, and demonstrate that the device is most sensitive for the highest scattering materials.

Light scattering of semitransparent sintered polytetrafluoroethylene films
TL;DR: The present authors found that the scattering coefficient of PTFE should exceed 1200 cm(-1), which is much greater than that of biological tissues, and the absorption coefficient must be less than 0.01 cm-thick, a necessary condition to achieve R > or =0.98 with a 10-mm-th thick slab.

Radiative transfer of luminescence light in biological tissue
TL;DR: Optically detected tissue changes are mostly based on the absorption contrast that is caused by intrinsic tissue chromophores, and the optical contrast of the detected images is, however, relatively poor due to the multiple scattered light inside tissue.

The Optics of Human Skin
R. Rox Anderson,John A. Parrish +1 more
TL;DR: An integrated review of the transfer of optical radiation into human skin is presented, aimed at developing useful models for photomedicine.

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.
Journal ArticleDOI
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.
