Paper Abstract

In this work, quality-limiting factors and optimum packing techniques in fiber bundles are studied, and they are applied to the design of imaging endoscopes in order to improve the image quality and achieve an optimum design, so that medical praxis based on these devices can be developed in a more reliable way. Quality-limiting factors in fiber bundles for medical imaging are analised. We find that leaky modes and interference between the optical fibers of the bundle have a close relationship with the length of the endoscope and opto-geometrical parameters of the fiber. They can be reduced using a steady state modes exciter and using a certain value of the distance between cores and the core diameter, respectively, as it will be studied. Optimum packing of the fibers is also very important to maximize the image area. We propose some structures and their efficiency is analised. It will be neccesary to reach an arrangement between core diameter, size of the cladding, and number of rings in the fiber bundle.
