Abstract: An imaging system comprises a first charge-coupled device (CCD), a second CCD, and a processor. The first CCD is configured to receive one or more light flashes, record a first set of data based on the light flashes, shift the first set of data in a first direction, read out the first set of data, and read out continuously. The second CCD is configured to receive the one or more light flashes, record a second set of data based on the light flashes, shift the second set of data in a second direction opposite to the first direction, read out the second set of data, and read out continuously. The processor, coupled to the first CCD and second CCD, is configured to determine a time and a location of the one or more light flashes based on the first set of data and the second set of data.

Abstract: A gamma vector camera is described for detecting and determining the energy spectrum of a gamma ray source and the direction to the gamma ray source. The gamma vector camera includes a detection system that records a track of a recoil electron produced by a Compton-scattering of an incident gamma ray emitted by the gamma ray source. A processor is configured to determine the energy and the direction of the recoil electron based on the track of the recoil electron recorded by the detection system, and to determine the energy spectrum of the gamma ray source and the direction to the gamma ray source based on the determined energies and directions of a plurality of recoil electrons produced by the Compton-scatterings of a respective plurality of incident gamma rays.

Abstract: A neutron source detector is provided for detecting and determining an energy spectrum of a neutron source and a direction to the neutron source. The neutron source detector includes a detection system configured to detect and record the location and energy of interaction between a detector and a recoil proton produced by a scattering of a neutron emitted by the neutron source. A processor is configured to determine the energy of each of a plurality of recoil protons produced by respective scatterings of a neutron based on the recorded locations and energies of interactions of the recoil protons and determine and order scatter locations of the scattered neutron based on the determined energies of the recoil protons. A direction of the scattered neutron is determined based on the order of the scatter locations.

Abstract: A photon generating event capture system is configured to capture light photons. Image intensifiers are arranged to amplify light photons and sensors are arranged to capture the amplified light photons. A control system detects the amplification of light photons by the image intensifiers. Upon detecting amplification, the control system deactivates the image intensifiers to shutdown further light photon amplification and switches the sensors from a clear mode to an acquisition mode within a period of time less than a decay time of the image intensifiers. The locations and intensities of the amplified light photons are then captured and read out by the sensors. By operating the sensors in a clear mode prior to detecting amplification of light photons, noise recorded by the sensors prior to the detection of light photon amplification is either shifted out of the sensor prior to the photon generating event or is smeared across the sensor data.

Abstract: Disclosed is a weld inspection system that utilizes an automated digital radiographic camera and control system to generate and review digital X-ray images of the weld seam. The weld inspection system is mountable onto the weld fixture, such that the weld inspection system can inspect welds upon completion of welding operations while the barrel panels are still clamped in the weld fixture. The digital radiographic camera includes a fiber optic scintillator x-ray to light conversion screen coupled to a high resolution charged coupled device (CCD) camera to produce digital radiographic images of a portion of the weld between welded barrel panels. An X-ray source is located in a shielded housing which is attached to a carriage that is movably mounted to the vertical weld fixture on the convex side of the barrel weld. The digital radiographic camera is attached to a carriage that is movably mounted to the vertical weld fixture on the concave side of the barrel weld.

Abstract: An object (10) to be radiographically inspected is irradiated in a sequence of different positions with respect to an X-ray beam emitted by a single source (12). A single X-ray detector in an imaging system (13) produces a series of electronic signals corresponding to the sequence of positions at which irradiation of the test object (10) occurs. The series of electronic signals is converted to a pair of series of signals, wherein one series of the pair is delayed with respect to the other series of the pair. The pair of series of signals is displayed as a stereoscopic pair of series of visual images corresponding to different positions at which the test object (10) is irradiated by the X-ray beam. A viewing system (19) causes each eye of an observer to see a different series of visual images, whereby the observer is enabled to preceive a series of stereoscopic X-ray images of the test object (10).
