Producing binary diffraction gratings in the double-diffraction system

In this paper, a method — based on the diffraction of light — for producing binary diffraction gratings is presented. It is shown that using two master gratings of the Ronchi type and utilizing the results of the double diffraction system it is possible to produce binary gratings with an arbitrary opening ratio. The results have been extended for a two-dimensional case and it is shown that producing binary grid gratings with arbitrary opening ratios in both x and y directions is also possible.
