Abstract
Capabilities of beam shaping with diffractive optics are substantially improved by a concept of crossed zones. We generalized the map transformation design of beam shapers by additional set of diffractive zone borders orthogonal to phase isolines. Application of nonlinear transformation to diffractive grooves profile, provided another method of building crossed-zones. Computer simulation results confirm feasibility and flexibility of the proposed approach.
