Abstract

Design of diffractive optical element for generating desired optical intensity distribution on an arbitrarily curved surface is investigated. The diffracted field distribution on a curved surface generated by a diffractive optical element is described by the non-invertible Fresnel transform. The conventional iterative Fourier transform algorithm is inappropriate for the design problem with the non-invertible Fresnel transform. The practical applicability of the nonlinear conjugate gradient method for this design problem is studied. It is shown that the nonlinear conjugate gradient method is practicable and effective for this kind of diffractive optical element design.
