A study is carried out to understand better the effect of apertures towards spatial and angular/directional dynamics of
light scattered from a scattering medium at different planes of observations. Several types of aperture such as circular,
semi-circular and annular aperture are considered. The investigation is done within the context of a reflectance mode
confocal microscope based on a 4-f optical system. A Monte Carlo simulation method to describe the focusing and
propagation of light in a turbid medium is adopted. A mechanism based on direction cosines is applied to simulate
photon propagation through different planes within the microscope system. The spatial distribution and spatial frequency
distribution (directional cosine) profile coupled with scattering statistics from such photonic simulations are observed
and discussed.
A study is carried out to better understand the spatial properties of light scattered from a turbid medium. The investigation is done within the context of a reflectance mode confocal microscope based on a 4-f optical system. A Monte Carlo simulation to describe the focusing and propagation of light in a turbid medium is adopted. The spatial distribution and phase space profile of the photons on different strategic planes within the system are observed and discussed. Scattering information such as scattering coefficient and the number of scattering events are matched with some of the simulation parameters to produce important information and hence their implications.
