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

A review of attenuation correction techniques for tissue fluorescence
TL;DR: This paper reviews currently available correction techniques with emphasis on clinical application and consideration given to the intrinsic accuracy and limitations of each technique.
Patent
Method and apparatus for improving image clarity and sensitivity in optical coherence tomography using dynamic feedback to control focal properties and coherence gating
TL;DR: In this article, a real-time dynamic optical feedback is used to detect the surface position of a tissue sample with respect to a reference point and the necessary delay scan range using a tilting/rotating mirror actuated by a voltage adjustable galvanometer.

In vivo skin optical clearing by glycerol solutions: mechanism.
TL;DR: It can be concluded that the thickness decrease of dermis and corresponding more regular packing of tissue fibers plays an important role in the mechanism for glycerol‐induced optical clearing of skin in vivo.
Journal ArticleDOI
The use of a neural network to determine tissue optical properties from spatially resolved diffuse reflectance measurements.
TL;DR: A novel application of a neural network to perform curve fitting to simulated experimental data, obviating the need for lengthy non-linear least-squares fitting procedures in the non-invasive determination of tissue optical properties.
Patent
Process, system and software arrangement for determining at least one location in a sample using an optical coherence tomography
TL;DR: In this article, a system, process and software arrangement are provided to determine at least one position of at least a portion of a sample, which is associated with an interference signal that includes a first electro-magnetic radiation received from the sample and a second electromagnetic signal received from a reference.

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.
Journal ArticleDOI
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.
