Wave-front control and aberration correction with a diffractive optical element.
A method that permits aberration correction and wave-front reshaping with a diffractive optical element (DOE) is described. Two aligned DOE's made of two different dispersive materials are used. The different dispersions of the two materials in addition to freedom in choosing their thicknesses enables the chromatic aberration and the wave fronts to be manipulated. Design and simulation of such DOE's are described.
