I read on Wikipedia that a hologram is made by superimposing a second wavefront ("reference beam") on the wavefront of interest, thus the image "animates" when moved.

I would like to know if more than one wavefront can be used, to create a smoother or more complicated animation ?

The hologram relies on the interference between the reference beam and the reflection from the target which is the source of the image. Using more beams would change the phase of the interference and tend to disrupt the image

Would it be possible to add more images so there were more than just two states ?

Do you mean like a neural network?

 

I meant for a smoother animation.
