Angle-dependent light scattering in the case of thin bone layers for the application of optical cochlear implants — •Tom Witke¹, Fabian Teichert^2,3,4, and Angela Thränhardt¹ — ¹Institute of Physics, Chemnitz University of Technology, Chemnitz, Germany — ²Fraunhofer Institute for Electronic Nano Systems (ENAS), Chemnitz, Germany — ³Center for Microtechnologies, Chemnitz University of Technology, Chemnitz, Germany — ⁴Center for Materials, Architectures and Integration of Nanomembranes (MAIN), Chemnitz University of Technology, Chemnitz, Germany

Understanding light scattering in human tissue is essential for the further development of optical cochlear implants. We investigate this using Monte-Carlo simulations and an analytical approach. The focus in simulation and analytics is on the investigation of phase functions that can model the properties of tissue best. Here we will present a phase function that has the same precision as a calculated distribution and yet has all the advantages of an analytical function, and show how multiple scattering and corresponding transmissions can be calculated analytically and compared with Monte-Carlo simulations.
