title: Use of a lensed fiber for a large-field-of-view, high-resolution, fiber-scanning microendoscope.
abstract: We report the application of a lensed fiber to a miniaturized fiber raster scanner in order to reduce the fiber's output beam size, thereby allowing for a compact and flexible endoscope capable of a large field of view (FOV) and high spatial resolution. For a proof of principle, the fabricated lensed fiber scanner is paired with a miniaturized gradient-index assembly to achieve a one-photon lateral resolution of 1.1 μm with a FOV that has a diameter of 440 μm.
