Measurement of Gradient Index Materials by Beam Deflection, Displacement, or Mode Conversion (Journal Version)

Abstract

For media with heterogenous 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.
