Light field imaging, which is one of the noncontact flame measurement methods, can capture and record multiangle radiative intensity information of a flame through a single shot. After the postprocessing and integration of the flame information, the

© 2018 Society for Industrial and Applied Mathematics. We develop a new Monte Carlo method that solves hyperbolic transport equations with stiff terms, characterized by a (small) scaling parameter. In particular, we focus on systems which lead to a

A Monte Carlo method for angle scattering of electrons in air that accommodates the small-angle multiple scattering and larger-angle single scattering limits is introduced. The algorithm is designed for use in a particle-in-cell simulation of electro

Calculations of detector response functions are complicated because they include the intricacies of signal creation from the detector itself as well as a complex interplay between the detector, the particle-emitting target, and the entire experimenta

We develop a theory of volumetric density estimation which generalizes prior photon point (0D) and beam (1D) approaches to a broader class of estimators using " n D" samples along photon and/or camera subpaths. Volumetric photon mapping performs dens

In this work, photon fluencies have been used to explore the depth of buried layers for diffuse optical tomography (DOT) systems. Back-reflected diffuse reflectance data were generated by Monte Carlo Modelling of Light Transport (MCMLT) simulations.

Dispersion properties of photon density waves propagating in seawater from a unidirectional point source have been studied using the Monte Carlo technique. It is shown that the spatial distribution of irradiance of the photon density waves at high mo

This paper proposes a Monte Carlo (MC) based angular distribution estimation method of multiply scattered photons for underwater imaging. This method targets on turbid waters. Our method is based on applying typical Monte Carlo ideas to the present p
