Hi, What is the appearance in the image of a fiberscope,

Has anyone looked thru one? Thanks.

Probably darkness on the side corresponding to the inside of the bend.

There's likely little correlation between location in the fiber bundle and
image pixel location except near the ends though.

Since the OP called it a fibrescope or endoscope, I assume it's an imaging bundle, where the relative position of the fibres is constant, is it not? There might be some mild moving around, but the fibres are unlikely to be really tangled up even in the middle, I would have thought--not that I've ever broken one.

Even illumination bundles are less random than you might think--in the ones I've looked at, the input-output position mapping happens in chunks, not fibre-by-fibre.
