Aberrations of the point spread function of a multimode fiber due to partial mode excitation
| Abstract | We investigate the point spread function of a multimode fiber. Thedistortion of the focal spot created on the fiber output facet isstudied for a variety of the parameters. We develop a theoretical modelof wavefront shaping through a multimode fiber and use it to confirm ourexperimental results and analyze the nature of the focal distortions. Weshow that aberration-free imaging with a large field of view can beachieved by using an appropriate number of segments on the spatial lightmodulator during the wavefront-shaping procedure. The results describeaberration limits for imaging with multimode fibers as in, e.g.,microendoscopy. |
