Abstract

The quality of microendoscopic images ((phi) < 0.5 mm) results from numerous factors. The microlens, the optical interfaces, and the multicore fiber (MCF) play a role. The intercomparison of the performances of these various components requires a precise evaluation of their modulation transfer function (MTF). The MTFs of a representative sample of MCFs have been evaluated in detail and the results presented in previous communications. The sampling density, the cross-talk, and to a lesser extent the leaky modes and propagation in the cladding have been found to be the main factors worsening the MTF. The Selfoc Grin lens also limits, in a non-negligible proportion, the overall quality of the microendoscopic image. Comparative data have been obtained with a slightly modified evaluation procedure for the MTF. This synthetic analysis results in a global understanding of the factors limiting the performances of microendoscopes.
