Abstract: The application discloses a system and methods for remote access and analysis of data collected about items under inspection. The system includes a data collection station, that may include an X-ray scanner, that scans the items under inspection to obtain data about the items. The data is transmitted to one or more remote expert stations, where a remote expert analyzes the data to determine whether the item contains a potential threat, such as, for example, explosives or other contraband.

Abstract: An inspection system and methods for inspecting items using terahertz radiation that may be used to detect contraband (e.g., explosives, weapons and drugs) within items under inspection. Terahertz radiation may be transmitted through and/or reflected from an item. The density and/or a physical property of one or more regions within an item may be determined. Terahertz radiation may be used to inspect surface regions of an item and/or other regions of an item. Terahertz radiation may used in combination with and/or in addition to another inspection modality.

Abstract: Methods, systems, and apparatus for transmitting a first set of continuous wave (CW) signals, where each CW signal of the first set of CW signals has a first signal frequency and the transmitter is turned off between transmission of each CW signal of the first set of CW signals. For each CW signal of the first set of CW signals, receiving a reflection of the CW signal, and selecting an analog to digital (A/D) sample of the reflection of the CW signal that does not contain ground reflections by selecting the A/D sample based on timing from the transmitter being turned off after transmission of the CW signal. Integrating the selected A/D samples from each of the CW signals of the first set of CW signals to obtain a single A/D sample for the first set of CW signals.

Abstract: An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.

Abstract: Radiation is directed at an object, and radiation scattered by the object is sensed. An angular distribution of scatter in the sensed scattered radiation relative to a path of the radiation directed at the object is determined, and the angular distribution is evaluated. One or more atomic numbers, or effective atomic numbers, of materials composing the object is determined based on evaluating the angular distribution.

Abstract: An inspection system that makes dual energy measurements with a detector array that has selective placement of filter elements adjacent a subset of detectors in the array to provide at least two subsets of detector elements sensitive to X-rays of different energies. Dual energy measurements may be made on objects of interest within an item under inspection by forming a volumetric image using measurements from detectors in a first of the subsets and synthetic readings computed from measurements made with detectors in the array, including those that are filtered. The volumetric image may be used to identify the objects of interest to and source points that, for each object of interest, provide a low interference path to one of the detectors in the second of the subsets. Measurements made with radiation emanating from those source points are used for dual energy analysis of the objects of interest.

Abstract: A volumetric image of a space is acquired from an imaging system. The space includes an object of interest and another object, and the volumetric image includes data representing the object of interest and the other object. A two-dimensional radiograph of the space is acquired from the imaging system. The two-dimensional radiograph of the space includes data representing the object of interest and the other object. The two-dimensional radiograph and the volumetric image are compared at the imaging system. A two-dimensional image is generated based on the comparison. The generated two-dimensional image includes the object of interest and excludes the other object.

Abstract: An imaging apparatus may include an interrogating apparatus, such as a scanner, configured to transmit toward and receive from a test subject in a target position, electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz. The interrogating apparatus or scanner may produce an image signal representative of the received radiation. A controller may store in memory reference-image data for at least one reference subject. The controller may produce test-image data from the image signal and may compare at least a portion of the test-image data with at least a portion of the reference-image data for the at least one reference subject.

Abstract: An object within a region is exposed to a first beam of penetrating radiation. The first beam of penetrating radiation is sensed on a side opposite the region from a source of the first beam. An attenuation of the first beam caused by passing the first beam through the object is determined, the attenuation is compared to a threshold attenuation. If the attenuation exceeds the threshold attenuation, a parameter of a second of beam of penetrating radiation is adjusted based on the determined attenuation.
