Abstract: A detection system for an x-ray or charged particle imaging system utilizes high bandgap, direct conversion x-ray detection materials. The signal of the x-ray/charged particle projection is recorded in a spatial light modulator such as a liquid crystal (LC) light valve. The light valve is then read-out by a polarized light optical microscope and a high speed camera. The camera is used to track the blooming spots in the light valve to resolve their intensity, and relate that intensity of the input x-ray photon or charged particle. This allows of spatially resolved, imaging, x-ray and/or charged particle spectrometer.

Abstract: A detection system for an x-ray microscopy system utilizes high bandgap, direct conversion x-ray detection materials. The signal of the x-ray projection is recorded in a spatial light modulator such as a liquid crystal (LC) light valve. The light valve is then read-out by a polarized light optical microscope. This configuration will mitigate the loss of light in the optical system over the current scintillator-optical microscope-camera detection systems.

Abstract: An amplifier for amplification of an electrical signal comprises an electro-optic (EO) medium for receiving the electrical signal, wherein applying the electrical signal to the EO medium causes a change to an effective index of refraction, a device configured for measuring a light phase change for measuring the change to the effective index of refraction, and a photodetector configured to convert the change to the effective index of refraction into an amplified electrical current output signal.

Abstract: A volumetric imaging device for constructing a three dimensional image includes a source, and absorbing detector, and an image constructor. The source includes a photon source, and a scatter detector arranged between the object and the photon source. The photon source emits photons towards the scatter detector. The scatter detector scatters at least some of the photons and detects the scattered photons. The object scatters at least some of the photons that were first scattered by the scatter detector. The absorbing detector is arranged to detect scattered photons from the object. The image constructor constructs the three dimensional image based on the scattered photons.

Abstract: A tetrahedron beam computed tomography system including an x ray source array that sequentially emits a plurality of x ray beams at different positions along a scanning direction and a collimator that intercepts the plurality of x-ray beams so that a plurality of fan-shaped x-ray beams emanate from the collimator towards an object. The system includes a first detector receiving a first set of fan-shaped x ray beams after they pass through the object, the first detector generating a first imaging signal for each of the received first set of fan-shaped x-ray beams and a second detector receiving a second set of fan-shaped x ray beams after they pass through the object, the second detector generating a second imaging signal for each of the received second set of fan-shaped x-ray beams. Each detector and source pair form a tetrahedral volume. In other embodiments, the system may also have more than two detectors arrays and/or more than one source array.
