Abstract

Coherent fiber bundles used in endoscopic imaging suffer from inter-core dispersion resulting in pseudo random phase distortions for a transmitted wavefront. This limits their application to relaying intensity patterns for pixelated, 2D near field imaging. In the last years, employing spatial light modulators for digital optical conjugation of these distortions and unpixellated 3D raster scanning has been demonstrated. Here we present using 2-Photon Polymerization for writing phase compensation holograms onto the CFB facet enabling direct far field imaging in a simplified and robust manner. Robustness and field of view were increased by aperiodic and twisted fibers.
