Re: [ATM] Flat Testing

[Hugues.Laroche@ses-astra.com]

Hola Alfredo,

You may have a look to
http://serge.bertorello.free.fr/plan/plan.html

where the 1-2-3 method is explained and in particular the testing of the 3
mirrors
one against the other. In short you get 3 euqations with 3 unknown which
are the
true curvatures, and that can be solved to get those. With a master flat,
you get
of course the curvature with a single test.

Sorry, it is in French, but you might use an automatic translator to get an
idea
of the meaning, for example babelfish.

Good luck

Hugues
