Coherent Bundles — Basic Theory

In the previous chapters the properties of systems have been discussed in which the optical fibre assembly has been used purely as a means of transferring light flux between a number of points. In these systems, little heed was paid to the optical isolation of a fibre from its neighbours, i.e. the fact that the light output from an optical fibre is a function solely of the light input to that fibre. Because of this isolation, any variation in the intensity of light across the input end of a light guide will manifest itself as a variation in intensity across the output face. However, these variations will not correlate simply, since the position of any fibre in the input face of the bundle is not related in a simple manner to its position in the output face.
