Propagation and reconstruction return an array of complex quantities, so the background will depend on which real quantity you are plotting: amplitude, phase, or intensity. Plotting the phase, for example, will show variations in the background with z. Variations in background can also arise from out-of-focus objects.
Using calc_holo to calculate the particle hologram and hp.propagate to reconstructe in different z, it was found that the z-background grayscale changed significantly.
holo = calc_holo(detector, sphere, medium_index, illum_wavelen, illum_polarization=(0, 1), theory='auto') rec_vol = hp.propagate(holo, z)
As shown in the following figure: rec_vol_1000 rec_vol_1500 Does anyone know why?
