  • Patent number: 11029418
    Abstract: Methods and apparatus for calibrating radioactive sources are described. An array of scintillation detectors forms a receptacle within which a sample or sample container can be retained by a holder. The scintillation detectors are coupled via light transducers such as photomultiplier tubes (PMTs) to independent electronic counters. Coincidence processing of time-tagged events yields a correlated event rate. One or more corrections can be applied as needed, for background counts, deadtime, or random coincidences. Voltage tuning of PMTs yields improved reproducibility. Accuracy of 1% has been demonstrated over a range of 10 kBq-3 MBq.

  • Patent number: 11022548
    Abstract: A device for holding samples to be analyzed using the infrared transmission spectroscopy comprised of three or more infrared transparent windows that creates unparalleled gaps while maintaining a consistent path length, which eliminates interference fringes and ensures that quantitative analysis can be achieved. The present invention allows the use of high refractive index material, silicon, as window material. The device using silicon windows can serve both purposes of sample storage and infrared measuring cell. All-purpose disposable sample holders are now possible. In one embodiment, a pre-assembled sample holder is most suitable for loading and analyzing flowable liquid samples. In another embodiment, a sample holder can be easily assembled after high-viscosity fluids and deformable solid samples are loaded. In an alternative embodiment, the device comprised of two or more infrared transparent windows and a reflective mirror can be used for quantitative analysis using transflection infrared spectroscopy.

  • Patent number: 11020273
    Abstract: A laser system calibration method and system are provided. In some methods, a calibration plate may be used to calibrate a video camera of the laser system. The video camera pixel locations may be mapped to the physical space. A xy-scan device of the laser system may be calibrated by defining control parameters for actuating components of the xy-scan device to scan a beam to a series of locations. Optionally, the beam may be scanned to a series of locations on a fluorescent plate. The video camera may be used to capture reflected light from the fluorescent plate. The xy-scan device may then be calibrated by mapping the xy-scan device control parameters to physical locations. A desired z-depth focus may be determined by defining control parameters for focusing a beam to different depths. The video camera or a confocal detector may be used to detect the scanned depths.

  • Patent number: 10989820
    Abstract: Disclosed herein is a radiation detector, comprising: a radiation absorption layer comprising an electrode; a voltage comparator that compares a voltage of the electrode to a first threshold; a counter that registers a number of photons of radiation absorbed by the radiation absorption layer; a controller; and a voltmeter.

The controller is configured to cause the voltmeter to measure the voltage upon expiration of the time delay. The controller is configured to determine the number of photons by dividing the voltage measured by the voltmeter by a voltage that a single photon would have caused on the electrode. The controller can cause the number registered by the counter to increase by the number of photons.
