I think I would expect a true light field display to work like a planar fourier capture array but in reverse

basically each pixel has a ton of micro-pixels, that emit light in different spread harmonics. you can imagine each pixel being sent a fourier transform of the shape of light that should be emitting from it

@SuricrasiaOnline I'm imagining an optical phased array and vibrating several feet into the air

@cinebox that's almost the idea except each sub-pixel has a fixed phase tunings or however you might call it


@SuricrasiaOnline would this also be capable of arbitrary-frequency color

@cinebox I don't think so. iirc from the paper the structure of the receivers (in my idea, the emitters) have to be tuned based on the expected frequency of the light coming in, because they work on the principle of interference

@SuricrasiaOnline this sounds, frighteningly plausible to construct the more I read about PFCAs

@SuricrasiaOnline I think this is basically just a fun physics trick for doing phased arrays by letting physics do all your fancy math
