Abstract
We discuss the symmetry properties of the Ambiguity Function. Next, we use it as a design tool for increasing the depth of field of imaging systems. We present a family of anti-symmetric phase-only masks that extend the depth of field of an optical system. We compute several Optical Transfer Functions with focus errors, and we report numerical simulations of the images that can be achieved using our proposed phase-only filters.
