Talk:Interferometric visibility

Fringe visibility

Fringe visibility redirects here, but the article doesn't mention it. Is it equivalent? If so, it should be listed with the other alternate names. Weisstein's encyclopedia says that fringe visibility is sometimes called Michelson fringe visibility, so it should be included too. -- Kjkolb 10:38, 27 November 2005 (UTC)

Incorrect equation?

Isn't the second equation in the article (reproduced below) missing a factor of 2 since $avg={\frac {max+min}{2}}$?
$Visibility(real)={\frac {max-min}{max+min}}$
Making this correction would result in the equation changing to:
$Visibility(real)=2\times {\frac {max-min}{max+min}}$

No, the current version of the equation is correct. This is the most common definition of visibility that I have seen. In the current definition, the visibility ranges from 0 to 1, whereas in yours it ranges from 0 to 2. Since visibility is often reported as a percentage, the current definition works better. --J S Lundeen (talk) 09:31, 30 June 2008 (UTC)
