Image quality in fiber bundle-based imaging systems is inherently limited by the size and spacing of the individual fiber cores. The fiber bundle limits the achievable spatial resolution and superimposes a fixed pattern of signal variability across the image. To overcome these limitations, piezoelectric tubes were used to synchronously dither the fiber bundle on both ends. Experimental results using the dithering approach with a commercial fiber bundle showed a substantial decrease in fixed pattern noise and an increase in spatial resolution.
