Other examples include chebyshevu, legendrep, jacobip, ultrasphericalc, hermiteh and laguerrel. For expansion, it supports usage as quasi-arrays where one axis is continuous and the other axis is ...

Specifically, the proposed metasurface works as polarizer arrays at two distinct wavelengths (i.e., 510 and 620 nm) with orthogonal polarization direction, and the mixture of these two colors with ...

Before the CCD camera, a linear polarizer P 2 with a 45° polarization azimuth is located on the beam path of the object and reference waves to convert the two into the same polarization. The object ...
