Radiative transfer equations with varying refractive index: a mathematical perspective.
نویسنده
چکیده
Established mathematical techniques to model the energy density of high-frequency waves in random media by radiative transfer equations and to model the small mean-free-path limit of radiative transfer solutions by diffusion equations are reviewed. These techniques are then applied to the derivation of radiative transfer and diffusion equations for the radiance, also known as specific intensity, of electromagnetic waves in situations where the refractive index of the underlying structure varies smoothly in space.

The photon transport equation for turbid biological media with spatially varying isotropic refractive index.
Using the principle of energy conservation and laws of geometrical optics, we derive the photon transport equation for turbid biological media with spatially varying isotropic refractive index. We show that when the refractive index is constant, our result reduces to the standard radiative transfer equation and when the medium is lossless and free of scattering to the well known geometrical opt...
متن کاملOn derivation of the radiative transfer equation and its diffusion approximation for scattering media with spatially varying refractive indices
Traditionally, the radiative transfer equation and its diffusion approximation are derived for a medium with a spatially constant refractive index (Ishimaru 1978 Wave Propagation and Scattering in Random Medial vol 1 (New York: Academic)). In this paper, we derive the radiative transport equation and its diffusion approximation relevant to optical tomography for a medium with a spatially varyin...
متن کاملSolution of Radiative Transfer Equation with a Continuous and Stochastic Varying Refractive Index by Legendre Transform Method
The present paper gives a new computational framework within which radiative transfer in a varying refractive index biological tissue can be studied. In our previous works, Legendre transform was used as an innovative view to handle the angular derivative terms in the case of uniform refractive index spherical medium. In biomedical optics, our analysis can be considered as a forward problem sol...
متن کاملValidity conditions for the radiative transfer equation.
We compare the radiative transfer equation for media with constant refractive index with the radiative transfer equation for media with spatially varying refractive indices [J. Opt. A Pure App. Opt. 1, L1 (1999)] and obtain approximate conditions under which the former equation is accurate for modeling light propagation in scattering media with spatially varying refractive indices. These condit...
متن کاملThe Geometry of Radiative Transfer
Radiative transfer describes the transport of electromagnetic energy in macroscopic environments when polarization effects are neglected [38]. The theory originates in work by Bouguer [6, 7] and Lambert [23] in the 18th century where the intensity of light and its measurement were first studied systematically, cf. Fig. 1, and in the 19th and early 20th century the theory was extended to include...
