Points-connecting neural network ray tracing

Not Accessible

Your library or personal account may give you access

Abstract

Unsupervised neural network ray tracing (NNRT) to calculate a light ray path connecting given points in a gradient-index medium is proposed here. If two points are given, the NNRT can provide a light ray path passing through these points without knowledge of the light ray direction. Maxwell’s fisheye lens having a spherical gradient-index is used to demonstrate how well the NNRT works. Light rays calculated using the NNRT are shown to trace an ideal path passing through given points.
