“…This variable refers to the scattering angle and how a photon would be directed as a result of scattering event. Initially, uniform random numbers ( N ) were generated between 0 and 1, and these uniform random numbers were forced into a non-uniform pattern by using it as a Probability Distribution Function (PDF) [ 33 ]. This PDF is a non-negative function such that P ( x ) dx is the probability (a number between 0 and 1) that x has a value between intervals x 1 and x 2 .…”

Issues related to human coronaviru s ( SARS CoV-2 ) are a burning topic of research in present times. Due to its easily contagious nature, real experimentation under laboratory conditions requires a high level of biosafety. A powerful algorithm serves as a potential tool for the analysis of these particles. We attempted to simulate the light scattering from coronavirus ( SARS CoV-2 ) model. Different images were modelled using a modified version of a Monte Carlo code. The results indicate that spikes on the viruses exhibit a significant scattering profile and that the presence of spikes during modelling contributes to the distinctiveness of the scattering profiles.

“…The analysis model was showed in Fig.6. When the beam passes through particles, diffracted light is calculated by using straight optical path, which is not considered the refraction (Fig.6 (a)), because we just consider the forward scattering so that we can use the geometrical optics approximation to compute the propagated beam [7] [8].…”

For the optical sensing in random media, an annular beam was used because of its nondiffractive feature. In our previous work, we have confirmed the nondiffractive effect of the annular beam in diluted solution of milk as random media. In the experiment of this study, increment of the nondiffractive effect has been confirmed by using the pulsed annular beam. We have simulated propagation characteristics of the annular beam in random media by wave analysis method. The attenuation rate and the forward scattering pattern of the propagation beam were calculated, and it showed agreement by comparing them with results of the experiment.

“…However, different from a laser, the transmitted rays originate from a surface light source. To simulate the surface light source, the complex Monte Carlo method [15,16] is always used to determine its distribution. Fortunately, a fiber can focus surface rays like a convex because of its cylindrical shape.…”

A high-precision automatic state monitoring and abnormity alarm technique is proposed to solve the process improvement issues of fiber-optic coil winding and splicing. Industrial cameras are used to capture optical and hot images during the assembly of optical components of a fiber-optic gyroscope. A line and contour analysis technique is used to detect abnormal winding. By analyzing the intensity distribution of transmitted light, the graph cut model and multivariate Gaussian mixture model are used to detect and segment the splicing defects. The practical applications indicate the correctness and accuracy of our vision-based technique.
