I think your idea could possibly work if the tejescopecend had some boosting like with a photomultiplier tube of some sort

obviously there would be an interpolation problem packing the cylinders at the ends but at the same time it doesn't seem to matter for endoscopes

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

my understanding was the fibres were considerably more than one 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

oh weird then how many strands have to be in an endoscope?

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. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3163080/ …pic.twitter.com/bp3izPFKkN

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