The image generated is pretty low resolution and is only in grey scale, but it’s pretty impressive what can be done with some basic hardware. The heart of the camera is the image sensor.

In a recent study, researchers developed a portable digital holographic camera system that can obtain full-color digital holograms of objects illuminated with spatially and temporally incoherent light ...

Effectively, this could simulate multiple lenses using just one hardware lens ... One feature Apple may have to omit due to the single-camera setup is spatial video. This capability relies ...
