  • Publication number: 20170067782
    Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus based on a high repetition rate pulsed laser. The laser produces a train of laser pulses at a high repetition rate in the kHz or even higher range. When the laser beam hits the sample, it generates several thousands of micro-plasma emissions per second. Synchronized miniature CCD array optical spectrometer modules collect the LIBS signal from these micro-plasma emissions. By adjusting the integration time of the spectrometer to cover a plurality of periods of the laser pulse train, the spectrometer integrates the LIBS signal produced by this plurality of laser pulses. Hence the intensity of the obtained LIBS spectrum can be greatly improved to increase the signal-to-noise ratio (SNR) and lower the limit of detection (LOD).

  • Patent number: 9504847
    Abstract: An improved method for performing phototherapy. The method comprises a step of applying a supplement to the patient before/after light treatment, which produces nitric oxide in the subject biological tissue to be treated. The nitric oxide serves as signaling molecules to cause vasodilatation and increase blood flow and micro-circulation in the biological tissue so as to enhance the effect and reduce the required treatment time of phototherapy.

  • Patent number: 9498640
    Abstract: A phototherapy apparatus with interactive user interface for treating biological tissue of an animal or human target. The user interface comprises intuitive graphic menus which allow the clinicians or practitioners to define the properties of the biological tissue through easily observable physical characteristics such as weight, skin color, and hair color of the patient. The central control unit of the phototherapy apparatus then automatically optimizes the parameters of the light source according to the properties of the biological tissue and generates an appropriate treatment protocol to produce the optimum phototherapy result.

  • Patent number: 9370465
    Abstract: This invention relates to a smart IV bag with a structurally integrated optical tag for IV drug identification and monitoring. The optical tag comprises a flow cell with a fluid channel in communication with the IV bag to sample a portion of the IV fluid onto an optical surface embedded in the flow cell. The optical surface causes a light beam to interact with the sampled IV fluid to produce a spectroscopic signal. The spectroscopic signal is then analyzed to obtain the content and concentration information of the IV fluid. Unlike traditional IV bag labels, the optical tag provides real-time, in-situ monitoring of IV fluid content and concentration, which greatly reduces the risk of mislabeling induced IV error.

  • Patent number: 9366634
    Abstract: This invention discloses a substrate enhanced laser-induced breakdown spectroscopy (LIBS) apparatus for liquid analysis. The LIBS apparatus comprises a pulsed laser for producing a laser beam, a substrate made of a material having a high absorption coefficient at the laser wavelength for receiving the liquid sample, an optical lens or mirror for focusing the laser beam onto the liquid sample to produce a plasma emission, and a spectrometer for measuring the optical spectrum of the plasma emission. When the thickness of the liquid sample reaches an optimum value, the plasma emission from the liquid sample is enhanced by the substrate to produce a strong LIBS signal for spectral analysis.

  • Publication number: 20150346103
    Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus and method for performing spectral imaging of a sample surface. A high repetition rate pulsed laser is employed to produce a train of laser pulses. The laser beam is then scanned by a scanning mechanism over a surface of the subject sample. Each laser pulse produces a LIBS signal from a specific position of the sample surface, which is then measured by a spectrometer device to obtain a LIBS spectrum. The position of the laser beam is recorded and correlated to the corresponding LIBS spectrum. A two dimensional (2-D) mapping of the sample surface to its LIBS spectra is acquired in this manner to construct a LIBS spectral image of the sample surface.
