title: Halftone screen design methods for nonlinear optical processing.
abstract: Specially designed halftone screens have been used to achieve nonlinear transformations of light intensity in a coherent optical system. Problems associated with the optimum design of suitable screens are discussed. Key performance criteria and improved design algorithms are presented with numerical results.
