摘要： A wide-area motion imaging system provides 360° persistent surveillance with a camera array that is small, light-weight, and operates at low power. The camera array is mounted on a tethered drone, which can hover at heights of up to 400', and includes small imagers fitted with lenses of different fixed focal lengths. The tether provides power, communication, and a data link from the camera array to a ground processing server that receives, processes and stores the imagery. The server also collects absolute and relative position data from a global positioning system (GPS) receiver and an inertial measurement unit (IMU) carried by the drone. The server uses this position data to correct the rolling shutter effect and to stabilize and georectify the final images, which can be stitched together and shown to a user live or in playback via a separate user interface.

摘要： Devices and methods for collimation of a penetrating radiation source, such as an x- ray source, for the purpose of creating a scanning beam, as might be employed for purposes of imaging. A first scanning element, constrained to move about a first axis, has at least one aperture for scanning radiation from inside the first scanning element to outside the first scanning element. A second- scanning element constrained to move with respect to a second axis, typically identical to the first, has at least one aperture for scanning radiation that has been transmitted through the first scanning element across a region of an inspected object.

摘要： A variable-geometry backscatter inspection system has a radiation detector array including one or more backscatter radiation detectors. The position of a second backscatter radiation detector is variable with respect to the position of a first backscatter radiation detector, so that the size of the detector array may be varied by moving the second radiation detector into or out of a predefined alignment with the first radiation detector. The system may include a movable base, and at least one of the detectors is movable with respect to the base. Methods of inspecting an object include forming a detector array by moving a second radiation detector into a predefined alignment with a first radiation detector, illuminating the object with a pencil beam of penetrating radiation, and detecting backscattered radiation with the detector array.

摘要： Systems and methods for inspecting an object with a scanned beam of penetrating radiation are disclosed. Scattered radiation from the beam is detected, in either the backward or forward direction. Characteristic values of the backscattered radiation are compared to expected reference values to characterize the object. Additionally, penetrating radiation transmitted through the inspected object may be combined with scatter information. In certain embodiments, the inspected field of view is less than 0.1 steradians, and the detector is separate from the source of penetrating radiation and is disposed, with respect to the object, such as to subtend greater than 0.5 steradians in the field of view of the object.
