Considering equal probability for any orientation, the average can be calculated in the case of two-dimensional fractals by integrating over all directions of the scattering vector q = (p,s): langle f p, s) rangle = frac{1}{2pi} int_{0}^{2pi}f q,phi mathrm{d}phi, (25).
To determine the bias direction of the photon scattering in any of the tissue layers, we first calculate the apparent position of the detector in each layer using the paraxial approximation.
where θ p accounts for the main direction of the AOA scatter components.
This importance sampling method applies multiple biases in the direction of photon scattering towards the apparent position of the OCT collecting fiber.
The scattering events, which take place at the end of the random steps, are produced by two random angles that determine the future direction of the photon packet scattering in three-dimensional space.
This implies that the properties of the focal volume are dictated primarily by the number of scattering events and that the direction of scattering plays a relatively minor role.
Moreover, the biased scatterings in this method can only produce scatterings in the half-sphere along the apparent direction of the collecting optics, as opposed to scattering in all directions as in the previous method.
The changes in direction of the neutron spin that take place on scattering by a magnetic interaction vector are highly dependent on their relative directions.
The surface scattering or reflecting light has the same polarization direction as the incident light, but the polarization direction of the transmission light is changed after being scattered by SSD, such as cracks and pores.
The background field, U B, is caused by light that is scattered within the tissue, from outside the nominal focus, but due to the re-direction of multiple scattering, is collected by the objective and focused to the pinhole.
