The cochlea forms a key element of the human auditory system in the
temporal bone. Damage to the cochlea continues to produce significant
impairment for sensory reception of environmental stimuli. To improve
this impairment, the optical cochlear implant forms a new research
approach. A prerequisite for this method is to understand how light
propagation, as well as scattering, reflection and absorption, takes
place within the cochlea. We offer a method to study the light
distribution in the human cochlea through phantom materials and
Monte-Carlo simulations. The calculation of an angular distribution
after scattering requires a phase function. Often approximate functions
like Henyey-Greenstein, two-term Henyey-Greenstein or Legendre
polynomial decompositions are used as phase function. An alternative is
to exactly calculate a Mie distribution for each scattering event. This
method provides a better fit to the data measured in this work.
