[ATM] Round Robin Mirror C images posted

[Dale Eason <atmpob@yahoo.com>]

I have uploaded  Foucault images and Ronchi images I
took of Round Robin Mirror C.

The top level directory can be found here:
http://www.atmlist.net/contrib/atmpob-at-yahoo-dot-com/Round%20Robin%20C/

The Foucault images are taken with my robo program of
the mirror without mask about every .006 inches from
ROC to .060 inches out.  The file name has the
position encoded as test14_0_xxx.png  where xxx is the
position in thousanths of an inch.  If the first
underscore is replaced by a minus then the measurement
is negative from 0.  Zero is not quite at ROC but a
little further out from it.

The dark parallel vertical lines are diffractions from
camera/lens artifacts.

I find the images taken close to center intersesting
in that the center seems to be flat ( a sphere).
Mirror C is 6 inch 64.5 ROC.  

For example:

The Ronchi images are taken using a 100 line screen. 
The position of the screen is also encoded into the
image name.  In this case the "p" in the name is the
decimal point.  These images were taken about every .1
inch except for one at .05.

I am not a good ronchi analysist.  I also have a 150
screen and can make images closer together if anyone
is interested.

Eventually I will post simulated Foucault images based
on the interferometry I have done.
