For media with heterogeneous index of refraction, rays follow curved paths. This paper describes methods exploiting knowledge of the relationship between refractive index distribution and ray paths to estimate the refractive index distribution based on laser beam deflection, displacement, and mode conversion on passage through the media. The work covers axial, radial (cylindrical), and spherical refractive index distributions.
