Freeform gradient-index media reconstruction
V. Chávez-Islas, F. H. Maldonado-Villamizar, E. Espíndola-Ramos +2
Reconstructing a gradient-index (GRIN) medium consists of determining a spatial refractive index distribution that produces a prescribed ray trajectory, an inverse problem in geome…

Generalized vectorial ray tracing for optical analysis and design in freeform gradient-index media
V. Chávez-Islas, E. Espíndola-Ramos, F. H. Maldonado-Villamizar +2
Gradient-index (GRIN) media with freeform refractive-index distributions require ray tracing approaches capable of accurately modeling light propagation in complex three-dimensiona…
