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

Frequency doubling of ultrashort laser pulses in biological tissues.
TL;DR: Experimental results indicate that the intensity of second-harmonic generation varies significantly among tissue types and between test sites in individual tissue.

A new phase function approximating to Mie scattering for radiative transport equations
TL;DR: A new scattering phase function is presented to approximate the accurate phase function from Mie theory, and an analytical result for the integral term of the equation is obtained for highly aligned beams, which may lead to a semi-analytical solution to the time-dependent radiative transport equation for time-resolved spectroscopy.

Two-versus one photon excitation laser scanning microscopy: critical importance of excitation wavelength.
TL;DR: It is concluded that optimising TPE conditions is essential for realizing the full benefits of this approach and improved cell survival and tissue penetration relative to conventional one-photon excitation confocal scanning laser microscopy.

Principles of laser microdissection and catapulting of histologic specimens and live cells.
TL;DR: Time-resolved photography of live-cell catapulting revealed that in defocused catapulting strong shear forces originate from the flow of the thin layer of culture medium covering the cells, and pulses focused at the periphery of the specimen cause a fast rotational movement that makes the specimen wind its way out of the culture medium, thereby undergoing much less shear stresses.

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.
