Having difficulty with Interferogram generation using Nest 4B

Hi all,

I am using Nest 4B and having difficulty with Interferogram generation.  I am using the complicated picture of TerraSAR-X to produce the interferogram. All the previous steps are fine, I actually performed the coregistered_stack step, however, when I go to "Computation of complex Interferogram", I have an error at the "2 -interferogram" table (I think). There is no description of the error and all the software does to alert you of an error is show the icon in the colour red!

I am baffled by this does anybody know what the peculiar error is?

We need two beams for making interferrogram. One beam provides the wave front and the other beam is the test beam. The test beam passes through the optical medium to be tested. You need to adjust the wavelength and the refractive index of the two beams properly. You are not giving the correct values. Adjust that and the problem will be solved. Set the interpolation degree. Try various values and check which one is working. That might be the other solution. Else, as discussed above the problem might be in image and the resolution might not be good enough to create the wave front.
