title: Design of gradient-index microlenses for stacked planar optics.
abstract: The refractive-index profiles of planar matrix microlenses that result from the Luneburg lens theory turn out to yield considerable aberrations. The presented modification of the design process enables satisfactory suppression of the focusing errors.
