TLDR
In this paper, an inspection system for detecting the presence of selected crystalline materials, such as explosives or drugs, utilizing an x-ray source and a collimated array of detectors to sense radiation scattered by the objects being inspected.Abstract:
An inspection system for detecting the presence of selected crystalline materials, such as explosives or drugs, utilizing an x-ray source and a collimated array of detectors to sense radiation scattered by the objects being inspected. A signal processing system compares the measured signal with selected spectra to determine whether specific materials are present within the inspected object.read more

Detection of concealed explosives and contraband
TL;DR: In this article, a detector for detection of concealed explosives, drugs and contraband using x-rays imaging and powder pattern techniques and ultrasonics is presented. But this detector is not suitable for carry-on baggage.
Patent
Detecting explosives or other contraband by employing transmitted and scattered x-rays
TL;DR: An X-ray inspection device (10) for detecting a specific material of interest in items of various sizes and shapes (24A, 24B, 24C) includes an Xray source system located at an inspection region and constructed to expose the examined item to at least one beam of Xray radiation, and one or more Xray detection systems (60, 80, 100).
Patent
Detecting contraband by employing interactive multiprobe tomography
TL;DR: In this paper, a multi-view X-ray inspection probe employs X-rays transmitted through or scattered from an examined item (14A, 14B) to identify a suspicious region (155) inside the item.
Patent
Methods and systems for the rapid detection of concealed objects
TL;DR: In this article, the microwave array emits controllably directed microwave radiation toward an object under inspection, which absorbs radiation in a manner dependent upon its metal content, and the microwave radiation absorption can be used to generate a measurement of metal content.
Patent
X-ray backscatter imaging system including moving body tracking assembly
TL;DR: In this paper, a tracking assembly is employed to rotate the scanning plane through a tracking angle and in a direction progressing from the entrance to the exit of the portal, through which the person passes, in order to substantially track the person or body as it moves with respect to the system.

X-ray imaging particularly adapted for low Z materials
Martin Annis,Paul Bjorkholm +1 more
TL;DR: An imaging device for increasing the ability to recognize, in x-ray produced images, materials of low atomic number was presented in this paper, where at least a pair of X-ray detectors were employed, each pair associated with signal processing apparatus and a display.
Patent
Container inspection system
TL;DR: A package inspection system is used for automatic inspection of a different content or identification of a content in a package such as a container especially a large container in unloading from a ship without opening or unpacking the container.

Radiant energy imaging with scanning pencil beam
Jay A Stein,Roderick D. Swift +1 more
TL;DR: In this paper, a pencil beam of X-rays scans an object along a line of direction before an X-ray detector produces an image of the line along a picture tube, by relatively displacing the object scanned and the line of scan in a direction transverse to the line-of-scan.
Patent
Dual energy imaging
TL;DR: In this article, two serially arranged detectors are used to develop simultaneous signals from transmitted energy of different characteristics, and the characteristics of the detectors may be selected to produce the desired effect, e.g., a gaseous detector may be pressurized in accordance with its function, a scintillating screen may be tilted or its length may be chosen to produce a desired absorption characteristic.
Patent
X-ray inspection device and method
TL;DR: In this paper, a security inspection apparatus designed for the safe, efficient and rapid inspection of products to detect the presence of objectionable X-ray detectable items is presented, which consists of a source of continuous X-rays of sufficiently low intensity that conventional photographic film is insensitive thereto, a fluoroscopic screen, a television camera adapted to transmit electrical impulses which provide a visual picture of the images on the fluoroscopy screen to a television monitor and means for intensifying the electrical impulses transmitted by the camera so that the image on the monitor is clearly visible.
