  • 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: 10302780
    Abstract: A fissile neutron detection system includes a neutron moderator and a neutron detector disposed proximate such that a majority of the surface area of the neutron moderator is disposed proximate the neutron detector. Fissile neutrons impinge upon and enter the neutron moderator where the energy level of the fissile neutron is reduced to that of a thermal neutron. The thermal neutron may exit the moderator in any direction. Maximizing the surface area of the neutron moderator that is proximate the neutron detector beneficially improves the reliability and accuracy of the fissile neutron detection system by increasing the percentage of thermal neutrons that exit the neutron moderator and enter the neutron detector.

  • Patent number: 10261347
    Abstract: A technique facilitates control over optical transmittance and, in some applications, the technique may be carried out without using moving mechanical parts. A system may comprise a light source and an optical fiber line, e.g. a plurality of optical fiber lines, in optical communication with the light source. An electrochromic device is positioned along each optical fiber line and may be selectively operated via electrical inputs to control optical transmittance along the corresponding optical fiber line. When plural optical fiber lines are employed, the corresponding plurality of electrochromic devices may be operated to also provide control over optical path selection. In fluid analysis operations, at least one sample chamber for receiving fluid samples may be positioned along a corresponding optical fiber line to enable analysis of light directed into the fluid sample as controlled by the corresponding electrochromic device.

  • Patent number: 10256600
    Abstract: The Hybrid Photonic Plasmonic Interconnect (HyPPI) combines both low loss photonic signal propagation and passive routing with ultra-compact plasmonic devices. These optical interconnects therefore uniquely combine fast operational data-bandwidths (in hundreds of Gbps) for light manipulation with low optical attenuation losses by hybridizing low loss photonics with strong light-matter-interaction plasmonics to create, modulate, switch and detect light efficiently at the same time. Initial implementations were considered for on-chip photonic integration, but also promising for free space or fiber-based systems. In general two technical options exist, which distinguished by the method the electric-optic conversion is executed: the extrinsic modulation method consists of an continuous wave source such as an LED or laser operating at steady power output, and signal encoding is done via an electro-optic modulator downstream of the source in the interconnect.

  • Patent number: 10254436
    Abstract: A scanning system, corresponding bracket and method are for scanning an object. The system has a frame defining a scanning chamber in which the object to be scanned is placed. The system also has a displacement assembly which displaces the object into and out of the scanning chamber. The system can also have a source which emits electromagnetic radiation or X-rays against the object within the scanning chamber such that the EM radiation passes through the object. The system can also have detectors arranged around the scanning chamber which detect the EM radiation which passes through the object. Each of the detectors forms a detector angle with a plane which can vary from one detector to the next. Similarly, the source can form an angle with the horizontal plane. The system, bracket, and method allow for the production of representative three-dimensional views of the object.
