Standard and non-standard metarefraction with confocal lenslet arrays
A recent paper demonstrated that two lenslet arrays with focal lengths f1 and f2, separated by f1 + f2, change the direction of transmitted light rays approximately like the interface between isotropic media with refractive indices n1 and n2, where n1/n2 = −f1/f2 [J. Courtial, New J. Phys. 10, 083033 (2008)]. This is true if light passes through corresponding lenslets, that is lenslets that sha...
متن کاملRay-optical refraction with confocal lenslet arrays
Two parallel lenslet arrays with focal lengths f1 and f2 that share a common focal plane (that is, which are separated by a distance f1 + f2) can refract transmitted light rays according to Snell’s law, but with the ‘sin’s replaced with ‘tan’s. This is the case for a limited range of input angles and other conditions. Such confocal lenslet arrays can therefore simulate the interface between opt...
متن کاملExperimental demonstration of ray-optical refraction with confocal lenslet arrays.
We observe imaging through windows comprising pairs of confocal lenslet arrays that have different focal lengths but that are otherwise identical. Image space is stretched in the longitudinal direction only. Such windows are examples of METATOYs, optical components that can change light-ray direction in ways that appear wave-optically forbidden.
متن کاملStandard and non-standard primordial neutrinos
The standard cosmological model predicts the existence of a cosmic neutrino background (CνB) with a present density of about nν + nν̄ ≃ 110 cm per flavour, which affects big-bang nucleosynthesis (BBN), cosmic microwave background (CMB) anisotropies, and the evolution of large scale structures (LSS). We report on a precision calculation of the CνB properties including the modification introduced ...
متن کاملStandard and non-standard neutrino properties
I review the interpretation of solar and atmospheric neutrino data in terms neutrino oscillations and describe some ways to account for the required neutrino masses and mixing angles from first principles, both within topdown and bottom-up approaches. I also discuss non-oscillation phenomena such as ββ0ν which may probe the absolute scale of neutrino mass, and also reveal its Majorana nature. I...
