Hi, What is the appearance in the image of a fiberscope,
borescope or endoscope if there is a bending damage
where the cable is bend tighter than the allowered bending
radius. What are you supposed to see in the image?
Has anyone looked thru one? Thanks.

The specification on bend radius limits is usually set to avoid fiber
breakage. If you bend the fibers once there is probably not going to
be too much damage. However, repeated bending builds up stress,
eventually resulting in breakage of fibers.

Image dimming due to TIR being overcome depends on how close to the
fiber's NA your imaging system is working. This can easily be
determined through modeling, using an optical design program.
