DESIGN OF DIFFRACTIVE OPTICAL ELEMENTS MODULATING POLARIZATION

摘要

We discuss polarizing kinoforms - diffractive optical elements that modulate only the polarization of incident light and form desired intensity distributions at a pregiven distance. The surface microrelief of such optical elements has the form of a binary curvilinear diffraction grating with a constant period less than a wavelength. The energy efficiency of the elements is equivalent to that of conventional multilevel phase kinoforms. [References: 17]
