Abstract

Light finds a path from a source to a receiver even along a partially occluded channel, which may therefore involve diffuse and specular reflections to allow a signal to arrive at the receiver. Natural FSO channels often exist inside closed structures such as aircraft, satellites, and buildings. Direct, diffusely-reflected, and specularly-reflected paths can be analyzed to assess received intensities in various geometries, such as ducts, rooms, and multi-compartment structures. These calculations are important in choosing sensor network architectures for infrastructure sensing, determining impulse response to estimate usable channel bandwidth, and studying light leakage through openings in multicompartment structures. This presentation will describe both geometrical optics models for carrying out these analyses, as well as a "photon-kinetic-theory" technique for estimating light coupling from compartment to compartment in multicompartment structures connected by openings. The surface absorption and angular reflectance characteristics of surfaces are included in these analyses. Specific results for cylindrical ducts of various aspect ratios will be presented as well as for rectangular coupled compartments.
