Polarization diffractive elements displayed with liquid crystal spatial light modulators
In this work we present the analysis of polarization diffractive elements, and its experimental realization with a twisted nematic liquid-crystal spatial light modulator. We analyze different spatially variant polarization diffractive elements by an extension of the scalar Fourier optics theory to a...

In this work we present the analysis of polarization diffractive elements, and its experimental realization with a twisted nematic liquid-crystal spatial light modulator.
