In one embodiment, the invention provides an imaging device having a light source, a photo-sensor and a scanning assembly. In some embodiments, the lig ht source is fixedly mounted in the first end of an elongated sheath and is adapted for illuminating a target, and the photo-sensor is mounted on the scanning assembly, also in the first end of the elongated sheath, and is adapted to detect light energy from the target. In other embodiments, the light source is movably mounted and the detector is held stationary. In othe r embodiments, both the light source and the photo-sensor are movably mounted. The scanning devices synchronously capture light energy from each of a plurality locations on the target, the light energy resulting from illumination by the light source, and synchronously digitizes the output fro m the photo-sensor from each of the plurality of locations on the target to generate an image of the target.
