Abstract

Design techniques are described for diffractive optical elements that, at least in some instances, can permit the design of diffractive optical elements without high frequency features, or with a significantly reduced number of such features. Diffractive optical elements designed in accordance with the described techniques can, in some instances, be easier to manufacture and/or replicate.
