Techniques to generate depth profiles of a surface by means of moiré fringes have become well known in modern optics. Different mathematical theories of moiré depth contouring have been developed using either communication theory or geometric ray tracing. For the oblique shadow method it is shown that these theories can be unified in a closed mathematical analysis. The analysis is extended to the case of various media with different refractive indexes covering the surface of interest.
