  • Patent number: 11175417
    Abstract: A neutron detector including a plurality of layers of converter material and a plurality of layers of detector material. Each layer of converter material can be immediately adjacent to at least one layer of detector material and each layer of detector material can be immediately adjacent to at least one layer of converter material. The neutron detector may further include a read out integrated circuit (ROIC) that is electrically coupled to the plurality of layers of detector material. A value output by the ROIC may be indicative of a neutron interacting with a layer of converter material from amongst the plurality of layers of converter material.

  • Patent number: 10620326
    Abstract: Apparatus for detecting radiation includes a sensor medium disposed within a cavity in a silicon-based substrate. An electrode arrangement is provided for collecting charge generated within the sensor medium by interactions with impinging radiation and drifted through the sensor medium. The electrode arrangement is constituted, in part, by a silicon portion of the substrate that is doped to increase its electrical conductivity and that defines part of the cavity wall.

  • Patent number: 10547805
    Abstract: A pattern generator circuit includes a high-speed shift register and a non-overlap generator. The shift register is programmable to produce a pulse train of pulses having a defined pulse duration and a defined pulse-to-pulse interval. The non-overlap generator deserializes the incoming pulse train, and it produces a time-separated reset pulse based on the pulse train. The shift register is configured to permit the pulse durations and pulse-to-pulse interval to be selected arbitrarily over specified ranges in increments of a basic time unit that depends on the oscillator period.

  • Patent number: 10057521
    Abstract: A high-speed CMOS camera includes an array of pixel circuits coupled to a photodiode array, an oscillator circuit, and a pattern generator circuit. The pattern generator circuit includes a high speed shift register and a non-overlap generator. The shift register is programmable to produce a pulse train of trigger pulses that defines an interframe and a frame's shutter duration. The non-overlap generator deserializes the incoming pulse train of trigger pulses, and it produces a time-separated reset pulse based on the pulse train of trigger pulses. The shift register is configured to permit the frame durations and the interframe times to be selected arbitrarily over specified ranges in increments of a basic time unit that depends on the oscillator period.

  • Patent number: 9993894
    Abstract: An apparatus for detecting radiation is provided. In embodiments, at least one sensor is disposed on a surface of a wafer-like substrate. At least one sensor medium is fixed relative to the substrate, optically or electrically coupled to the sensor, and separated from the sensor by no more than the substrate thickness. An electronic signal-processing circuit is connected to the sensor and configured to produce an output when the sensor is stimulated by a product of an interaction between the sensor medium and impinging radiation. The sensor is configured to collect, from the sensor medium, charge and/or light produced within the sensor medium by interactions with impinging radiation.

  • Patent number: 9116249
    Abstract: An apparatus for detecting radiation is provided. In embodiments, at least one sensor medium is provided, of a kind that interacts with radiation to generate photons and/or charge carriers. The apparatus also includes at least one electrode arrangement configured to collect radiation-generated charge from a sensor medium that has been provided. The apparatus also includes at least one photodetector configured to produce an electrical output in response to photons generated by radiation in such a sensor medium, and an electronic circuit configured to produce an output that is jointly responsive to the collected charge and to the photodetector output. At least one such electrode arrangement, at least one such photodetector, and at least one such sensor medium are combined to form an integral unit.
