    Abstract: A wave guide face plate for transmitting an image formed in a scintillating material included as part of a transmitting medium is disclosed. The transmitting medium includes a random distribution of different refractive index regions in two orthogonal dimensions, and an essentially consistent refractive index in a third orthogonal dimension. The third orthogonal direction is aligned with a transmission axis of the wave transmitter extending from an input location to a wave detector location. The transmission efficiency of the wave guide faceplate is improved in situations where the entry angle of the input radiation is different from the axis of the wave transmitter as compared to conventional faceplates.

    Abstract: An imaging device (100) and an imaging method are described herein. By way of example, the imaging devices (100) includes a scintillator plate (200) configured to convert incident radiation into scintillation light and an imaging element (110) configured to convert the scintillation light to an electric signal. The scintillator plate (100) includes a first scintillator partitioned from a second scintillator by a divider in a direction perpendicular to a propagation direction of the incident radiation. The divider prevents first scintillation light generated in the first scintillator from diffusing into the second scintillator and second scintillation light generated in the first scintillator from diffusing into the first scintillator.

    Abstract: A radiation detector (24) for an imaging system includes a two-dimensional array (50) of nondeliquescent ceramic scintillating fibers or sheets (52). The scintillating fibers (52) are manufactured from a GOS ceramic material. Each scintillating fiber (52) has a width (d2) between 0.1 mm and I mm, a length (h2) between 0.1 mm and 2mm and a height (h8) between 1mm and 2mm. Such scintillating fiber (52) has a height (h8) to cross-sectional dimension (d2, h2) ratio of approximately 10 to 1. The scintillating fibers (52) are held together by layers (86, 96) of a low index coating material. A two-dimensional array (32) of photodiodes (34) is positioned adjacent and in optical communication with the scintillating fibers (52) to convert the visible light into electrical signals. A grid (28) is disposed by the scintillating array (50). The grid (28) has the apertures (30) which correspond to a cross-section of the photodiodes (34) and determine a spatial resolution of the imaging system.
