Abstract: An integrated device includes a laser ranging module, a dual-branched fiber bundle, a beam splitter, and an image receiving module. The laser ranging module includes a light source, an optical receiver and a computing unit. The fiber bundle is disposed between the laser ranging module and the beam splitter. A target reflects a measuring beam emitted by the light source to form a reflected beam. The beam splitter splits the reflected beam into a first reflected beam and a second reflected beam. The first reflected beam is transmitted to the optical receiver through the fiber bundle to generate a measurement signal. The computing unit receives the measurement signal to calculate a distance between the target and the fiber bundle. The image receiving module is disposed on the optical path of the second reflected beam to receive the second reflected beam and displays the image of the target.
