Abstract

Acoustic shadow moir\'e has unique properties to be used for many potential applications in medical diagnostics, manufacturing, and material characterization. In this paper, numerical analysis, using Comsol, is used to investigate the principles of acoustic moir\'e interference phenomenon. The study confirmed that the expected fringe images of shadow interference can be created at Talbot distances. The study confirms the experimental results reported by this group [1] and proves without any doubt that acoustic moir\'e interference phenomenon exists.
