Abstract
We describe the use of 2D binary gratings for encoding quadratic phase variations, which can generate bright spots of equal irradiance; both in the far-field (similar to Dammann gratings), and in the near-field (as Lohmann gratings). Experimental verifications are included. (C) 1 997 Elsevier Science B.V.
