  • Publication number: 20200408929
    Abstract: A neural network based corrector for photon counting detectors is described. A method for photon count correction includes receiving, by a trained artificial neural network (ANN), a detected photon count from a photon counting detector. The detected photon count corresponds to an attenuated energy spectrum. The attenuated energy spectrum is related to characteristics of an imaging object and is based, at least in part, on an incident energy spectrum. The method further includes correcting, by the trained ANN, the detected photon count to produce a corrected photon count. The method may include reconstructing, by image reconstruction circuitry, an image based, at least in part, on the corrected photon count.

  • Publication number: 20200408931
    Abstract: An approach for counting particles suspended in a flow of gas or liquid in instruments that direct the flow through an illuminated region. Pulses are detected when the signal is below a threshold amplitude and moves above the threshold amplitude. This movement above the threshold creates a dead time during which only one pulse is detected until the signal amplitude moves sufficiently below the threshold such that a subsequent particle creates a distinct pulse. After counting the number of pulses, and determining the measured live time that the signal is below the threshold value, an initial particle concentration is calculated, and the calculation corrected for coincidence by calculating an actual live time as a measured live time minus a constant multiplied by the number of distinctly counted pulses, where the constant has the units of time. From this, particle concentrations in a volume can be determined.

The angle-enhancing screens increase the field of view of an image projected thereon by a projection lens while maintaining an increased size of the projected image, by decreasing the size of picture elements making up the image while maintaining their pitch. In some embodiments, the angle-enhancing screen includes a field lens, such as a Fresnel field lens, for straightening the views of light projected thereon and a double lenslet array of matched lenslet pairs, each of the pairs including either two positive lenslets or one positive and one negative lenslet, for increasing the field of view. In another embodiment, the angle-enhancing screen may include a field lens and an array of four positive lenslet quartets. In a further embodiment, the field lens may be replaced with a Gabor superlens including two lenslet arrays of different pitches.

It also has a spectral transmittance wavelength interval which is as small as possible according to the requirements of the respective application and restricted by narrow blocking bands. The secondary bandpass filter is designed such that its transmittance wavelength interval is limited by a short-wave edge and a long-wave edge and is adjusted to the primary bandpass filter in such a way that its edges shift over the required angle range only within the blocking bands of the primary bandpass filter.
