In this paper we extend previous studies to further diffraction properties of Ronchi rulings. Our considerations are based on the physical theory of gratings with different strip-widths geometry. Under scope are absorptive gratings, phase gratings and mixed gratings. The case of gratings with diverse structures is also considered. In particular, gratings of phase with absorption (mixed gratings) are considered by means of the observed diffraction properties for absorption rulings as it is described in the work. Ronchigrams resulting for different grating parameters and different values from primary aberrations are shown. Some experimental results of Ronchi rulings for diverse structures are including. This study can be used not only for optical testing, but also for gratings of light for diffraction of atoms or to describe diffraction effects of micro-gratings.
