Multifocal refractive-diffractive optical elements, which produce arbitrary light distribution, are widely used in lightweight and compact optical systems. However, due to the lack of research on the diffraction aberration principle for multifocal re

Profile transformation of a uniform monochromatic beam with a flat wavefront after the propagation through an apodizer comprising a square serrated aperture and a spatial filter is theoretically considered at the apodizer exit and behind it. Main dif
