In this paper we use the combination of a Ronchi-Talbot grating interferometer with Moiré effect to investigate homogeneity and isotropy in transparent materials. A Ronchi grating is placed at the self-imaging position of the Ronchi-Talbot interferometer, and the magnifying property of the Moiré effect, helps to observe variations in the light wavefront passing through the sample. We use proper codes to analyze the Moiré fringes. The spatial resolution of our method is as small as micrometer in Moiré wave vector.
