continuous fft of camera feed not working

[Vaeryn]

I'm very new to LabView, and I've been working on a project for an upcoming experiment in my lab at my university. I'm trying to use Fourier analysis of an interference pattern to measure the shift of the fringes. I modified the low-level grab vi to include a continuous FFT of the image acquired from a camera feed, but the FFT appears to be outputting nothing. Can anyone tell me what I'm doing wrong?

Hi Vaeryn,

If you're still having problems could you tell us a bit more about your system (Hardware, Software, etc.)? In the meantime I was able to find this:

I hope this helps!
