Issues for hologram generation and reconstruction

[Arthur Dubois]

Hi,

I'm trying to generate holograms with sphere of ~50µm radius with the following detector  :

shape = 200, spacing = 5. The center of the sphere is (500, 500, 500) with a illumination wavelength of 0.532 µm,  and I got this result :

But the reconstruction with zstack = np.linspace(250, 750,  201) looks like this :

It seems that all the reconstruction slices are the same.

I used calc_holo() to generate the hologram and propagate() for the reconstruction slices.

For smaller particles (radius of 2 µm) the hologram and reconstruction seem to be normal.

Thanks for any help
