Claim 0:
1. An apparatus for determining an index of refraction of a material, comprising:
a tomography system comprising a light source to generate a beam of light; and
a processor comprising a tangible medium coupled to the tomography system and configured to receive data from the tomography system,
wherein the tangible medium embodies instructions to determine an index of refraction of the material in response to a location of a focal point of the beam, including to:
focus the light beam into the material to an intended focal point having an intended location;
identify a location of an interference signal of the focused light;
determine an index of refraction of the target material in response to the intended focal point location and the determined interference signal location; and
map the determined index of refraction to the location of the material.
