Monte Carlo Simulation Tool of Evanescent Waves Spectroscopy Fiber – Optic Probe for Medical Applications (FOPS 3D)

Optimization Efficiency of Monte Carlo Simulation Tool for Evanescent Wave Spectroscopy Fiber-Optic Probe

“…The verification case was a fiber (indices of refraction: n 1 = 1.46, n 2 = 1.34, and n cl = 1.45) 100 mm long and 0.9 mm thick, with a flattened section of 35 mm and conical tapered sections with a 6 • slope, where the thickness of the flattened section varied between 0.32 mm to 0.19 mm. The results showed an exact match between the old and new results [5], which allowed for validating the new version of FOPS 3D so that other conditions could be investigated.…”

“…In Figure 2, the simulation results for the given fiber properties (in the case of no bending angle) are shown. These results were presented in our previous works [4,5] and were actually used to validate all three versions of FOPS 3D and were also used as acceptance tests.…”

“…The verification phase in the software development process of the new version of the FOPS 3D simulation tool consisted of comparing the compatibility of its results with those of a previous work [5]. The verification case was a fiber (indices of refraction: n 1 = 1.46, n 2 = 1.34, and n cl = 1.45) 100 mm long and 0.9 mm thick, with a flattened section of 35 mm and conical tapered sections with a 6 • slope, where the thickness of the flattened section varied between 0.32 mm to 0.19 mm.…”

“…In a previous work, the Monte Carlo simulation tool (FOPS 3D) was described [5]; this tool can simulate the full three-dimensional geometrical structure of the fiber and the propagation of a light beam through it. Evanescent waves are formed when waves travelling through a medium undergo total internal reflections, on which the Attenuated Total Reflectance (ATR) sampling technique is based [1,6].…”
