  • Amending of fluorescence sensor signal localization in human skin by matching of the reflective index. 
    Churmakov, D. Y.; Meglinski, I. V.; Greenhalgh, D. A. (Society of Photo-optical Instrumentation Engineers, 2004-01-01)
    Fluorescence diagnostic techniques are notable amongst many other optical methods because they offer high sensitivity and non-invasive measurement of tissue properties. However, a combination of multiple scattering and ...
  • Analysis of skin tissues spatial fluorescence distribution by the Monte Carlo simulation 
    Churmakov, D. Y.; Meglinski, I. V.; Piletsky, Sergey A.; Greenhalgh, D. A. (Iop Publishing Ltd, 2003-07-21)
    A novel Monte Carlo technique of simulation of spatial fluorescence distribution within the human skin is presented. The computational model of skin takes into account the spatial distribution of fluorophores, which would ...
  • Flow imaging using femtosecond-laser-induced two-photon fluorescence 
    Kelman, J. B.; Greenhalgh, D. A.; Ramsay, Euan; Xiao, Dong; Reid, Derryck T. (Optical Society of America, 2004-08)
    A novel technique is demonstrated for the imaging of turbulent flows in which a single window to the flow is the only optical access required. A femtosecond laser is used to excite two-photon fluorescence in a disodium ...
  • Influence of refractive index matching on the photon diffuse reflectance 
    Churmakov, D. Y.; Meglinski, I. V.; Greenhalgh, D. A. (Iop Publishing Ltd, 2002-12-07)
    Photon migration in a randomly inhomogeneous, highly scattering and absorbing semi-infinitemediumwith a plane boundary is considered by aMonte Carlo (MC) technique. The employed MC technique combines the statistical ...
  • Low and high orders light scattering in particulate media 
    Meglinski, I. V.; Romanov, V. P.; Churmakov, D. Y.; Berrocal, Edouard; Jermy, Mark C.; Greenhalgh, D. A. (2004-07-12)
    We present the results of a theoretical study providing details of propagation of laser radiation within disperse randomly inhomogeneous intermediately single- to-multiple scattering media. A quantitative analysis of ...
  • Monte Carlo simulation of coherent effects in multiple scattering 
    Meglinski, I. V.; Kuzmin, Vladimir L.; Churmakov, D. Y.; Greenhalgh, D. A. (Royal Society, 2005-01-08)
    Using a combination of the stochastic Monte Carlo technique and the iteration procedure of the solution to the Bethe-Salpeter equation, it has been shown that the simulation of the optical path of a photon packet undergoing ...
