    Abstract: An X-ray detection system includes at least two electrodes constructed and cooperatively arranged at a photoconductive material to provide an electric field inside the material in a first direction, an X-ray shield and an X-ray window, a read-out circuitry, and a processing circuitry. The X-ray shield and the X-ray window are constructed and arranged to direct X-rays into the photoconductive material in a selected X-ray direction substantially different from the first direction, wherein the directed X-rays are absorbed at a location inside the photoconductive material at a depth corresponding to their energy. The read-out circuitry is constructed and arranged to receive electric signals corresponding to the absorption location inside the photoconductive material. The processing circuitry is constructed and arranged to determine the energy of the absorbed X-rays based on the electric signals.

    Abstract: A three-color QWIP focal plane array is based on a GaAs/AlGaAs material system. Three-color QWIPs (300) enable target recognition and discriminating systems to precisely obtain the temperature of two objects in the presence of a third unknown parameter. The QWIPs (300) are designed to reduce the normal reflection over a significant wavelength range. One aspect of the present invention involves two photon absorptions per transition in a double quantum well structure which is different from typical QWIP structures. This design is expected to significantly reduce the dark current as a result of higher thermionic barriers and therefore allow the devices to operate at elevated temperatures. The device is expected to be fabricated using a GaAs/AlxGa1-xAs material system on a semi-insulating GaAs substrate (340) by Molecular Beam Epitacy (MBE).

    Abstract: The invention provides a millimeter wave and far-infrared detector of extreme sensitivity and shorter response time. The detector comprises an input (1) for introducing incident millimeter wave or far-infrared radiation (2) to a detector antenna; a semiconductor substrate (4) on which is formed a single-electron transistor (14) for controlling the current penetrating a semiconductor quantum dot (12); and bow tie antennas (6, 6a, 6b, 6c) for concentrating millimeter wave or far-infrared radiation (2) onto a semiconductor quantum dot that define a submicron space in the single-electron transistor (14). The quantum dot forming a two-dimensional electron system efficiently absorbs the concentrated radiation and maintains the resulting excitation state for more than 10 nanoseconds so that more than 1,000,000 electrons can be transported for a single photon absorbed.

    Abstract: A shielding grid (44) constructed of a radiation absorbing material (46, 48) for use with an array of discreet, non-contiguous radiation sensors to protect such sensors from scattered radiation. The sensors each have a radiation sensitive area (11) with a width (Ws) and a length (W1). In designing the grid a prototile having a prototile width and a prototile length is developed. The prototile width is equal to the radiation sensitive area width divided by an integer, and the prototile length is also equal to the radiation sensitive area length divided by an integer. The prototile contains a motif contained solely within the prototile that forms a pattern when a plurality of prototiles sufficient to cover the array of discreet detector are arrayed contiguously. The grid is constructed with the radiation absorbing material in this pattern.

    Abstract: A radiation imager includes a photodetector array having topographically patterned surface features, which include support islands disposed over the active portion of one or more photodetectors in the photodetector array. A structured scintillator array having individual columnar scintillator elements is disposed in fixed relation to the photodetector array so that the individual scintillator elements are disposed on scintillator support islands. A barrier layer is disposed between the support islands and the photodetector array to minimize chemical interactions between the material forming the support island and the underlying photodetector array during the fabrication process. After the support islands have been patterned, the scintillator elements are grown by selectively depositing scintillator material on the support islands.

    Abstract: A photodetector is provided for sensing radiation in middle and long wave infrared domain. The sensor has a sensor layer of a first material having a first conductivity type and a first permittivity in which the shortest distance of any point in the sensor layer to an adjacent layer having a second conductivity type and a second permittivity lower than the first permittivity is 20 nanometres or less. Conductivity type may be semiconductor n-type or p-type or insulator. If, for example, a silicon sensor layer is sandwiched between two silicon oxide layers, the sensor layer of preferably p-type semiconductor has a maximum thickness of 40 nanometres. If a p-type layer of a first material is sandwiched between a dielectric layer with the second permittivity and an n-type layer of the first material, the maximum thickness is 20 nanometres. Spaced apart, two contacts are provided in contact with the sensor layer.
