This is extremely interesting. What kind of SLM is that? As I'm sure you're aware 48 angles is unusually small for this kind of thing as most existing printers use (expensive) SLMs of at least XGA resolution, or 1024 horizontal angles; the limiting factor for resolution is generally the data pipeline and lighting setup rather than the printer hardware. But it sounds like you might be taking a radical approach.

ALso, are you targeting single or double parallax? Again the limiting factor there is usually software - there really needs to be a "Cura" of holography to properly democratize this (I am currently working on a Blender plugin, but that can't cover the entire scope).
