[Centroid] Reference spot for centroiding. #53

Closed faitdivers closed 10 years ago

faitdivers commented 10 years ago

To compute the centroid via the correlation method, the reference spot is given, I think, by the WFS part, when the propagation is done without any aberrations.

herminarto commented 10 years ago

I see.

for WFS part, can you provide me the intensity without any aberrations?

NKant13 commented 10 years ago

You can use the wfs function with a phase that is unity, this should provide you with an output that has no aberrations.

faitdivers commented 10 years ago

Do you mean zeros instead of unity, Nick?

Sorry you are right was thinking about the complex amplitude instead of only the phase. Although as long as the phase is constant this should be oke to create airy disks without aberrations.

Yes! Completely correct. Thanks for the heads up.
