Yeah even 1 megapixel implies a 1000x1000 square bundle if each fiber is one pixel. Unless each fiber can be more than 1 pixel

honestly i assumed "optical fibre" just meant a material that when bundled would faithfully conduct an image from one surface to another

Apparently not. It transmits a Gaussian corresponding to the fiber’s’ain mode so it’s 1 pixel per strand if I’m understanding correctly

Dunno. I’m now fairly confused. Digital is easy since it’s a light bitstream. This analog use case is tricky.

yeah weird i mean i thought a property of optical fibre was it would conduct whatever you put through it faithfully to the other side

I think I figured it out. Coherent fiber bundles can do what you think, but it’s 1 pixel/strand and they’re like 1mm cross section. I saw one device listed at 10k bundle (so 100x100). Apparently they’ve been increasingly replaced by ccd arrays at tip. ncbi.nlm.nih.gov/pmc/articles/P

one majro benefit of digital (resolution notwithstanding) is that you don't have to screw around with high-precision calibration
