Abstract

Fiber coherent bundles used in various instruments must provide for high quality image transfer. The primary defects, degrading the image quality, include the presence of broken fibers, which lead to troublesome dark dots in the view field, and so-called `grey' fibers (fibers have a partially reduced light transmission in the bundle). Both lead to a degradation of the local resolution capability of fiber-optic systems and to viewer discomfort who works with instruments in which these bundles are used. Such defects can be evaluated by the parameter-defect ratio, which is defined as amount ratio of defect fibers to total fibers. This paper describes a system designed for an objective and automatic evaluation of the defect ratio of fiber coherent bundles by a new method involving the image process.
