Devices, systems, and methods that utilize a technique of changing a position of the set of optical fibers of the fiber bundle in cooperation with the scanning of the imaging light across a proximal surface of the fiber bundle to improve the resolution of the scanned image. In particular, a bundle actuator can be provided to change a position of the set of optical fibers of the fiber bundle in cooperation with a scanning of the imaging light across the proximal surface of the fiber bundle to cover the areas of the gaps between the optical fibers and to increase a resolution of the scanned image.
