Coherent vs Incoherent Bundles

[dermite]

Hi there, I have an assessment task coming up soon, and one of the dot points assessed is:
•   discuss differences between the role of coherent and incoherent bundles of fibres in an endoscope.

So far, I have got the below information for this dot point. Is there any thing else I need to help which will increase my marks?

To transmit the image without any distortion requires a coherent bundle, which is one in which the individual optic fibres are kept in the same relative positions in the bundle at both ends. An incoherent bundle has the optical fibres arranged randomly; they are used for transmitting light to illuminate the organ/tissue but not an image.
----------------------------------------

Also, if a question regarding this dot point is asked, how many marks will it be, and where would the marks be given?

Hello!

I think you need to explore more on the role of coherent and incoherent bundles of fibres. Why do we need coherent bundles from the tissue to the outside? Why do we prefer to have incoherent bundles from the outside to the tissue?

As for marks, I wouldn't see this question going further than 4 marks. By identifying the differences between coherent and incoherent bundles, and comparing their uses in endoscopes.

Hope this helps! Keep asking away!
