Looked up “cromulent” in the dictionary. Wasn’t disappointed!!

The chances of a deal are said to be weeks away, if not non-existent.

What kind of non-sentence is that?

A couple of ideas:

Encoding holograms

• Model the object in 3D space (using Blender maybe?)
• Use the Angular Spectrum algorithm to model light propagation, its interaction with the object, and it hitting the recording medium.
• Your final recorded hologram should have two maps (aka “images”) across (x, y): a map of the light’s amplitude and another of its phase offset. This is your recorded hologram.

Decoding holograms:

• Use the angular spectrum algorithm again except reverse the light’s propagation direction. The amplitude and phase maps from the encoding phase are the initial conditions you’ll use for the light.
• The light’s amplitude and phase information you calculate at various planes above the recording plane are the 3D “reconstructed” image.

Last thought

Holography is often used to record information from the real world, and in that process it’s impossible to record the light’s phase during the encode step. Physicist’s call it “the phase problem” and there are all kinds of fancy tricks to try to get around it when decoding holograms in the computer. If you’re simulating everything from scratch then you have the luxury of recording the phase as well as the amplitude - and this should make decoding much easier as a result!
