Abstract

The question of the image quality evaluation in microendoscopy ((phi) < 0.5 mm) and of its improvements is addressed in this article. The MTF has been carefully evaluated by a precise and reproducible method and reveals significant differences between the various multicore fibers tested (twelve different fibers from three firms). The measuring conditions, such as the aperture of the incident light beam, the orientation of the sampling direction, and the position of the evaluation point on the bundle section, were also of concern in the evaluation of the image quality. The measurement of the overall contrast loss is related not only to the limit of sampling by the density of fiber cores, but also to the intercore fiber coupling.
