摘要：

A method for exploiting nonuniform ultrahigh spatial-frequency relief gratings as space-variant polarization elements is presented. In this method the local direction of the gratings determines the polarization angles, while the period of the gratings is controlled to ensure continuity of the grating function for any desired polarization operation. We illustrate the method with a specific space-variant half-wave plate for laser radiation of 10.6 mum.
