[edit] Experimental setup
Is this article talking about the classic double slit experiment or not? It seems to me that the relation derived is valid for this, but the text mentions lenses and what not which seem superfluous. --Michael C. Price talk 13:38, 16 November 2006 (UTC)
- I believe it is. The topic as a whole is a sub-topic of coherence theory, which deals with coherence and fringe visibility of different light sources. The physics of coherence is of separation of time or space (which is just a statement about speed of propagation of waves.) The book on Optics by Hecht and Zajac provides a solid introductory overview. Lenses show up typically to get the brightness big enough in the lab to be able to measure the things. What should probably be done is to contrast this relation against the framework of semi-coherent light sources. Other notable subtopics of coherence theory are Hanbury-Brown and Twiss effect. linas 15:36, 16 November 2006 (UTC)
