Abstract / Description:We present a miniature, flexible two−photon microscope consisting of a fused coherent optical fiber bundle with 30,000 cores and a gradient−index lens objective. The laser focus of a standard two−photon laser−scanning microscope was scanned over the entrance surface of the fiber bundle, resulting in sequential coupling into individual cores. Fluorescent light was detected through the fiber bundle. Micrometer−sized fluorescent beads and pollen grains were readily resolved. In addition, fluorescently labeled blood vessels were imaged through the fiber bundle in rat brain in vivo.
