Using multimode optical fibre in micro-endoscopy has both advantages and drawbacks. Especially small footprint of the fibre probe in the order of tens of micrometers in diameter, and possibility to modify the facet to obtain special optical and/or mechanical properties are important to minimize the penetration damage when imaging a tissue of living organisms. On the other hand, the imaging procedure requires complex optical apparatus for shaping of the light entering the fiber probe to eliminate the mode scrambling originated in different group velocities of particular modes, and an intricate preparation step - calibration process mapping input holographic patterns to output foci in the sample space. Both the calibration technique and the efficiency of the focusing the light at the distal end of the optical fiber will be discussed.
