  • Patent number: 9625310
    Abstract: A system includes a detector and a main processing unit having an event processing module. The detector includes pixels to detect an event corresponding to photon absorption. The event processing module is configured to read event information for each event detected by each pixel of the detector in order of receipt from the detector and to compare an energy level value in the event information for each event to a predetermined range of energy level values. An event is counted when the energy level value is within the predetermined range of energy level values. For each event having an energy level below the predetermined range, the energy level value for a next consecutive event in the received event information is read and a combined energy level value of the event and the next consecutive event is determined as well as the pixel locations of the event and the next consecutive event.

  • Patent number: 9581543
    Abstract: A device images radiation from a scene. A detector is sensitive to the radiation in a first wavelength band. A lens forms an image of the scene on the detector. A filtering arrangement includes two sets of radiation absorbing molecules. A control unit switches the filtering arrangement between two states. In the first state, all of the radiation in the first wavelength band is transmitted to the detector. In the second state, the radiation in a second wavelength band within the first wavelength band is absorbed by the radiation absorbing molecules. The control unit synchronizes the switching of the filtering arrangement with the detector. Each pixel of the image formed on the detector includes two signals. The first signal includes information from the scene radiation in the first wavelength band. The second signal excludes information from the scene radiation absorbed by the filtering arrangement in the second wavelength band.

  • Patent number: 9580327
    Abstract: Apparatus and methods for consolidating granular silicon and determining trace elements content of the consolidated silicon are disclosed. Silicon granules are placed in a vessel, and a silicon slug of known purity is embedded at least partially in the granules. The slug is preheated to a temperature sufficient to couple with an induction heater. As the silicon slug melts, silicon granules adjacent the molten silicon also melt. The vessel passes through an induction coil to successively inductively heat and melt regions of the silicon granules from the leading end to the trailing end with each region solidifying as the molten silicon exits the induction coil to provide a multicrystalline silicon ingot. The multicrystalline silicon ingot is sliced into wafers, which are analyzed by low-temperature Fourier transform infrared spectroscopy to determine levels of trace elements in the ingot.

  • Patent number: 9528924
    Abstract: A photodetection device has an optical module (4) that includes a light source (7), an excitation optical system, and a detection optical system and that two-dimensionally and relatively scans a transparent stage (5) in a first sampling direction and a second sampling direction intersecting the first sampling direction. A scan length in the first sampling direction is longer than a scan length in the second sampling direction. A data sampling unit in the detection optical system performs sampling for a distance of a second sampling interval during scanning in the second sampling direction, and performs sampling for a distance of a first sampling interval shorter than the distance of the second sampling interval during scanning in the first sampling direction. An aperture (10) of the excitation optical system sets a size in the first sampling direction of a spot shape of excitation light from the light source (7) to be smaller than a size in the second sampling direction.
