ABSTRACT:
An optical arrangement is provided for use in imaging with a large depth of focus. The optical arrangement comprises an aperture unit, and a replication unit. The replication unit is configured for producing a plurality of replicas of an input optical field passed through the aperture unit such that the replicas include at least two replicas that are of substantially the same phase distribution and are created at different regions of the aperture unit plane.
