The photoelastic modulator optical element has a large tolerance of the incident angle allowing more simple alignment of the system. As the light beam need not follow the principal axis of a rotating ...

This is a preview. Log in through your library . Abstract The history of astronomical photoelastic polarimeters is briefly outlined. A description is given of a system of this type which has been in ...

Metasurfaces are the two-dimensional equivalent of metamaterials, composing discrete subwavelength structures, possessing the capability of full control of light properties, such as amplitude, phase, ...
