Abstract
We conduct an experimental study of the effect of the side diffraction orders on the imaging quality produced by a refractive/diffractive digital-camera objective and determine the diffractive efficiency requirements for a diffractive lens with a single-layer, single-profile, sawtooth microstructure that eliminates the impact of side-diffraction-order aureole (halo) on image quality.
