All photon analysis of ultrasonically sculpted virtual optical waveguides using a custom-designed physics-based renderer

We discuss the characterization and analysis of ultrasonically sculpted virtual optical waveguides in scattering media using a novel physics-based renderer. Our renderer is physically accurate, unbiased, and fast. Unlike other simulators, our renderer can handle heterogeneous refractive index profiles in scattering media. Using the renderer, we characterized the effect of different parameters of virtual optical waveguides to enhance the overall light throughput in transparent and scattering media. The simulator can potentially be used for analysis-by-synthesis and design of innovative acousto-optics systems, capable of generating complex virtual elements in scattering media.
