Abstract
Preliminary results obtained from copying binary phase Dammann gratings onto DCG show that this is a promising method of fabricating compact, space invariant array generators. By starting from a 'master' grating it is possible to construct a wide range of DCG HOEs, taylor made for a specific application. Parameters, such as focal length and array dimensions, can easily be altered during recording. In addition the copied wavefront can be enhanced by spatial filtering techniques.
