| Résumé: | Binary diffractive optics have been extensively studied to date as tools for arbitrary laser beam shaping and
experimentally implemented with etched transparent optics and spatial light modulators. Here we demonstrate
that a simple one-step binary optic is able to enhance the intensity of a focused beam, displaying some counter-
intuitive focusing anomalies. We explain these effects by considering the optical aberrations in binary diffractive
optics and outline how this may be exploited for further improvements in refractive/diffractive combinations for
super-resolution microscopy |
