[ATM] Webcam Hartmann



2+ years of struggle have finally produced a program which will produce 2D 
mirror surface deviation contour plots from Hartmann-style images taken 
using one of the many available PC cameras (maybe even one of those 
expensive astro CCD cameras - anyone want to try?).  The following zip 
package contains the executable, source code, sample images, help file, and 
a processing walk-through:

(2004-02-25, Win32, 1.21 M)

The executable, like Diffract, requires qtintf.dll which I have posted for 
download:

Apparently I'm not the programmer I thought I was.  My FFT routine, used 
heavily in the program, is correct, but slow - Steve Koehler's runs 10x 
faster.  I'll try to speed up mine and post an improved version of the 
program; the above version will work for most mirrors, but gets sluggish 
for fast ones.
