  • Patent number: 10337996
    Abstract: The present invention relates to a Lidar surveying instrument, which is capable of detecting and discriminating laser-induced particle fluorescence of any biological or non-biological atmospheric particles. The present astrobiology sensing instrument can remotely sense and discriminate, in real-time, the bio-indicator aerosol material signatures and environmental interferents that exist in an extraterrestrial environment, such as Mars, in order to expand the search for signatures of extraterrestrial life from the planetary soil to the planetary ground level atmosphere, by performing atmospheric volume scans of hundreds of meters in a radial direction around a planetary vehicle or a spacecraft. The Lidar instrument technology of the present invention employs real-time aerosol particle detection and discrimination based on two physical variables: particle fluorescence and particle size in the bio-discrimination space.

  • Patent number: 10267728
    Abstract: A measurement system to measure a concentration of neutral gas species above a substrate includes a substrate support located in a chamber to support a substrate. A plasma source generates plasma in the chamber above the substrate. The plasma generates metastable species having higher ionization energy than a neutral gas species. The metastable species excite the neutral gas species located above the substrate. An optical emission spectrometer (OES) sensor measures spectra from a location above the substrate while the plasma is generated by the plasma source. A controller is configured to determine a concentration of the neutral gas species in a region above the substrate based on the measured spectra and to selectively process the substrate based on the concentration.

  • Patent number: 10219761
    Abstract: A multilayer staggered coupling collimator includes multiple collimating layers, multiple collimating orifices being provided on each collimating layer. At least two collimating layers are in a staggered coupling relationship. Compared with a single-layer collimator, the multilayer staggered coupling collimator can improve the performance, achieve multi-performance selection functions, and have a better machining feasibility. Since the thickness of each collimating layer is less after the collimator is divided into several collimating layers, the machining precision is easy to ensure.
