Using Geant4 toolkit for simulations of optical systems with roughisotropic surfaces using BRDF profiles
Original language description
The Geant4 toolkit is important and popular software for simulation of physics processes in various areas. In spite of its primary application in high-energy particle physics and astrophysics, it is also widely used for studies in space and medical science. The accuracy of Geant4 simulations depends on the credibility of both models of physics processes and the description of materials involved in simulations. In this work, model of rough isotropic optical surfaces is extended to Geant4 providing with the knowledge of their in-plane BRDF (Bidirectional Reflectance Distribution Function) scatter profile. We updated Geant4?s algorithm responsible for tracking photon on a boundary of two optical environments to reflect the scatter profile of isotropic optical surfaces. To examine reliability of models, we measured BRDF profile of Tyvek, mylar and glass mirror samples by means of CASI scatterometer.
