  • Patent number: 11487014
    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.

  • Publication number: 20170016769
    Abstract: The present invention provides a measurement system of real-time spatially-resolved spectrum and time-resolved spectrum and a measurement module thereof. The measurement system includes an excitation light and a measurement module. The excitation light excites a fluorescent sample and the measurement module receives and analyzes fluorescence emitted by the fluorescent sample. The measurement module includes a single-photon linear scanner and a linear CCD spectrometer. The single-photon linear scanner selectively intercepts a light beam component of a multi-wavelength light beam that has a predetermined wavelength to generate a single-wavelength time-resolved signal, wherein the multi-wavelength light beam is generated by splitting the fluorescence. The linear CCD spectrometer receives the multi-wavelength light beam and generates a spatially-resolved full-spectrum fluorescence signal.
