  • Patent number: 10274312
    Abstract: A system and device that measures a specimen's surface profile by passing a bright white light source through a series of lenses which generate repeatable chromatic focal shift variations of wavelengths of white light for Z axis measurements. The movement of the sensor along an X-Y raster pattern is controlled by a X-directional and Y-directional scanner used in combination with X and Y actuators. The system and device translate the chromatic focal shifts into digital data which may then be used to both control the position of the lenses along the surface of the specimen and generate a 3D topographical images of the specimens being profiled.

  • Patent number: 10274367
    Abstract: The effective spot size of a spectroscopic metrology device is reduced through deconvolution of a measurement spectra set acquired from a measurement target combined with a training spectra set obtained from a training target. The measurement spectra set may be obtained using sparse sampling of a grid scan of a measurement target. The training spectra set is obtained from a grid scan of a training target that is similar to the measurement target. The training spectra set and the measurement spectra set include spectra from different grid nodes. Deconvolution of the measurement spectra and the training spectra sets produces an estimated spectrum for the measurement target that is an estimate of a spectrum from the measurement target produced with incident light having an effective spot size that is smaller than the actual spot size. One or more characteristics of the measurement target may then be determined using the estimated spectrum.

  • Patent number: 10222315
    Abstract: Holograms of colloidal dispersions encode comprehensive information about individual particles' three-dimensional positions, sizes and optical properties. Extracting that information typically is computation-ally intensive, and thus slow. Machine-learning techniques based on support vector machines (SVMs) can analyze holographic video microscopy data in real time on low-power computers. The resulting stream of precise particle-resolved tracking and characterization data provides unparalleled insights into the composition and dynamics of colloidal dispersions and enables applications ranging from basic research to process control and quality assurance.

  • Patent number: 9618363
    Abstract: A specimen analysis system, a specimen analyzer, and a specimen analysis method are provided by which reexamination of a specimen can be executed more quickly than in conventional technology. A specimen analyzer measures a specimen and obtains an analysis result. The specimen analyzer determines the necessity of remeasurement of the specimen, based on a specimen analysis result. Also, the specimen analyzer determines, based on the specimen analysis result, whether or not determination of the necessity of remeasurement of the specimen based on examination information by the examination information management device is necessary. If it is determined that determination of the necessity of remeasurement of the specimen based on the examination information is necessary, the specimen analyzer makes a request to determine the necessity of remeasurement of the specimen based on the examination information, to the examination information management device.

  • Patent number: 9500827
    Abstract: Techniques and mechanisms for a monolithic photonic integrated circuit (PIC) to provide spectrometry functionality. In an embodiment, the PIC comprises a photonic device, a first waveguide and a second waveguide, wherein one of the first waveguide and the second waveguide includes a released portion which is free to move relative to a substrate of the PIC. During a metering cycle to evaluate a material under test, control logic operates an actuator to successively configure a plurality of positions of the released portion relative to the photonic device. In another embodiment, light from the first waveguide is variously diffracted by a grating of the photonic device during the metering cycle, where portions of the light are directed into the second waveguide. Different wavelengths of light diffracted into the second waveguide may be successively detected, for different positions of the released portion, to determine spectrometric measurements over a range of wavelength.

  • Patent number: 9470633
    Abstract: An apparatus for testing transmittance includes a sample unit to position a material under test. The material under test is disposed between respective flat surfaces of a first mount and a second mount, which are positioned in the sample unit for a test round. The sample unit defines a first volume and a second volume, wherein arc shapes, variously formed by respective surfaces of the first and second volume, conform to an imaginary circle. During the test round, a rotation unit successively changes an angular position of the MUT relative to a light source. A light detector receives light from the light source which has been transmitted through the first volume, the MUT and the second volume. Based on the received light, a transmittance signature of the MUT is determined for a range of incidence angles.

  • Patent number: 9404792
    Abstract: According to an embodiment of the disclosure, an optical sensor system comprises a mast, a mast mirror, a navigation unit, one or more faceted mirrors, and at least two beam-steering mirrors. The mast is elevated from a vehicle. The mast mirror reflects signals either to or from object space along a line of sight. The navigation unit determines a location and attitude of the mast mirror. The one or more faceted mirrors reflect an error sensing beam to reveal a flexure of the mast mirror. The at least two beam-steering mirrors prevent the line of sight for the signals reflected off the mast mirror from walking off the mast mirror by adjusting an angle and translation of the signals reflected off the mast mirror.

  • Patent number: 9366633
    Abstract: Multiple functional systems are integrated to configure a portable handheld decision-aid device for first responder medics. Fuzzy membership functions of “life” and “death” are used to determine the status of fallen people using remote measurements. EO/IR cameras can be used to detect and identify casualties in a mass injury situation, while also estimating body temperature. Using the temperature, along with the remote estimation of a second vital sign, the life membership proportion can be estimated from the ground truth by using a 2D projection of stable vital signs. The other fuzzy membership function, death, can be estimated by the presence or absence of peri-mortem and post-mortem molecules. These molecules are only released after death and provide a certain indication of death. Solid state UV laser resonance Raman backscattering from these molecules allows the device to analyze the molecules present in a plume around the casualty.

  • Patent number: 9335250
    Abstract: A method and apparatus is disclosed for suppression of bubbles in an optical measurement cell. A measurement cell is filled with a fluid sample. Valves connected through plumbing connections to the cell are operated such that any flow in and out of the cell is stopped. A pressure source is then applied through a valve and flow impedance mechanism to the liquid contained within the cell, causing any bubbles contained or generated within the cell to be dissolved back into solution or reduced in size such that optical measurements taken of the sample are more accurate and free of interference with the measurement beam and of measured stray light. Possible pressure sources include compressed gas, a piston, and a constant flow-rate pump.
