Gaussian particle distribution along optical axis investigation

p/b behavior investigation with normal distribution of the number of particles Np in each layer Ni by the number index of layer i. Object parameters (a): screen size 3.072 x 3.072 mm2, λ = 632.8 nm, Δz = 0.054 mm, N = 101, D = 0.054 mm, T = 0%. Discrete normal distribution (b) of the number of particles Np in the order of layers i. A typical dependence (c) of the p/b, calculated for i and i+1 layers of volume, on the layer number i
