An endoscope is a medical instrument used to examine the inside of a patient's body using optical fibres.
State the names of the two types of optical fibre bundle used in an endoscope. Compare their functions, and explain why cladding is essential for one of these bundles but not for the other.
In long-distance telecommunications, material and modal dispersion are significant issues that require mitigation. Discuss why the techniques used to reduce these types of dispersion are not necessary in an endoscope, and explain how implementing these techniques would negatively affect the performance of the endoscope.
