Experimental demonstration of a light-ray-direction-flipping METATOY based on confocal lenticular arrays
Michael Blair, Leo Clark, E. Alasdair Houston +4
We show, theoretically and experimentally, that a sheet formed by two confocal lenticular arrays can flip one component of the local light-ray direction. Ray-optically, such a shee…
Standard and non-standard metarefraction with confocal lenslet arrays
Johannes Courtial
A recent paper demonstrated that two lenslet arrays with focal lengths f_1 and f_2, separated by f_1 + f_2, change the direction of transmitted light rays approximately like the in…
Generalized refraction using lenslet arrays
Alasdair C. Hamilton, Johannes Courtial
We have recently started to investigate 2D arrays of confocal lens pairs. Miniaturization of the lens pairs can make the array behave ray-optically like a homogeneous medium. Here…
Geometric limits to geometric optical imaging with infinite, planar, non-absorbing sheets
Johannes Courtial
New ray-optical elements allow generalized refraction of light rays, but geometry imposes limitations on possible mappings between the positions of an object and its geometric imag…
