Ray-tracing method for isotropic inhomogeneous refractive-index media from arbitrary discrete input

Ray-tracing method for isotropic inhomogeneous refractive-index media from arbitrary discrete input: Yohei Nishidate, Takashi Nagata, Shin-ya Morita, Yutaka Yamagata
We have developed a ray-tracing simulation procedure for optically isotropic gradient refractive-index media. The procedure can take discrete points of arbitrary distribution for the definition of refractive-index distributions and lens surfaces. It is useful for simulating ray trajectories in real ...
