A variation of the Mach-Zehnder interferometric arrangement was used to show that both reversing and non reversing wave fronts produce peaks of the coherent function in the far zone when a beam splitter (such as a semi-mirror or a grating) is illuminated by diffuse laser light. The reversing case produces a much narrower coherent angle than the non-reversing case, which, in turn, can be much narrower than the diffuse radiant intensity pattern. A beam splitter hidden behind such a diffuser and detectable only by means of a coherent optical setup has potential applications for optical coding.
