摘要： A diffraction system configured to generate a diffraction signature based upon an angular disbursement of radiation is provided. In some embodiments, the diffraction system comprises a radiation source comprising a radiographic isotope configured to natural emit radiation due to decay. In some embodiment, the diffraction system is part of an object identification system that comprises one or more other radiation imaging modalities, such as a CT system and/or a line-scan system. By way of example, the one or more other radiation imaging modalities may perform an initial examination of an object to generate data indicative of the object. The data can be analyzed to identify an item of interest within the object, which can subsequently be examined by the diffraction system to generate a diffraction signature of the item. The diffraction signature of the item can be compared to known diffraction signatures of know items to characterize the item.

摘要： Techniques, systems and apparatus are described for a multimode passive detection system (MMPDS). A MMPDS includes a detector assembly of array of drift tubes arranged as detector modules to generate detector signal data representing electrical responses to cosmic ray charged particles passing through respective detector modules and traversing through a volume of interest (VOI). Detector circuitry measures the generated detector signal data and outputs the measured detector signal data as spatially segregated data streams corresponding to respective detector modules. A clock system distributes a master clock signal throughout the detector circuitry. A compute cluster including nodes of computing devices merges the spatially segregated data streams into temporally segregated data, obtains information on tracks of the cosmic ray charged particles based on the temporally segregated data, reconstructs an image of the volume of interest based on the obtained information, and identifies an object in the VOI based on the reconstructed image.

摘要： Human body back-scattering inspection systems and methods are disclosed. In the invention, X-rays modulated by the flying-spot forming unit having spirally distributed flying-spots have a distribution having alternating peaks and valleys on the irradiated surface. In this way, scanning starting times can be precisely controlled to cause two devices to have scanning starting times that are different by a half of a cycle. That is, the beams outputted from one device are at maximum when the beams outputted from the other device are at minimum. In other words, even if the ray source of one device emits rays, it will not significantly affect imaging result of the other device. In such way, the two devices may emit rays and perform scanning at the same time, and thus the total scanning time is reduced.

摘要： An X-ray backscatter imaging system uses frequency modulated X-rays to determine depth of features within a target. An X-ray source generates X-ray radiation modulated by a frequency-modulated bias current. The X-ray radiation impinges upon and is backscattered from multiple depths within the target. A scintillating material receives the backscattered X-rays and generates corresponding photons. A photodetector, having gain modulated by the frequency modulation signal from the local oscillator, receives the photons from the scintillating material and generates an analog output signal containing phase delay information indicative of the distance travelled by the X-rays backscattered from multiple depths within the target. The analog output signal is sampled by an analog-to-digital converter to create a digital output signal. A computer processor performs a discrete Fourier transform on the digital output signal to provide target depth information based on the phase delay information.
