    Ive been going through my book, but ive come across a question I can't answer:

    In a medical endoscope, the fibre bundle used to view the image is coherent.
    a) What is meant by a coherent fiber bundle?
    b) Explain why this fibre bundle needs to be coherent.

    Any help is great! Thanks.

    The positions of ends of the fibres at the internal end need to map exactly to the same positions at the viewing end. In other words, the fibres cannot be allowed to "tangle up" as they go through the cable. Otherwise, the image would also be "tangled up".
