    Abstract: A radiation conducting conduit functions as an off-axis filter and contrast enhancer for an imaging device. A core of transparent glass has an axis aligned with the line of sight of the device. Cladding is provided which has the same index of refraction and co-efficient of thermal expansion as the core glass, except that a small percentage of the cladding glass is made of thin fibers or leaves of absorbing glass aligned substantially radially to the axis of the conduit and distributed randomly in the volume of the cladding. The interface between the core glass and the cladding glass of the same composition does not involve reflection or refraction, and non-axial light passes through the interface and is trapped among the absorbing black fibers. There, it is reflected and diminuated until it is totally absorbed. The conduit may be formed by the steps of: forming a flat sheet of glass containing random parallel fibers or leaves of absorbing glass, cutting the sheet into beveled strips, assembling the strips into a cylindrical configuration with the absorbing elements extending radially of the axis, inserting a core of transparent glass, and fusing the assembly and core together.

    Abstract: An X-ray anti-scatter grid having thinner X-ray opaque layers, smaller X-ray opaque diameters, greater aspect ratio, lower weight and improved image resolution is disclosed. A method of forming the X-ray anti-scatter grid is disclosed that includes a set of hollow X-ray transparent glass capillary tubes that are fused together, with an X-ray opaque layer thick enough to block X-rays at a specified energy inside the capillary tubes. The capillary tubes provide the high aspect ratio and light weight, while the X-ray opaque layer is provided by a deposition process that has features similar to atomic layer deposition (ALD). The high aspect ratio and thin layers improves resolution and decreases image artifacts, and large area X-ray anti-scatter grids are provided by aligning the axis of the an X-ray opaque layers to the X-ray source.

    Abstract: A method of making a waveguiding optical component includes processing a polymer optical material to form a billet having an axis of light transmission and having residual stress maintaining a transverse extent of the billet; placing the billet into a mold, the mold being configured to constrain transverse expansion of the billet according to a desired shape of the waveguiding optical component; and heating the billet in the mold to induce relaxation of the residual stress and corresponding transverse expansion of the billet, thereby forming the billet into the waveguiding optical component with the desired shape. An alternative method begins with a collection of individual canes or fiber segments which are fused during the heating process, bypassing a separate process of forming a billet.

    Abstract: A proton radiography system includes a source of a proton beam at nonrelativistic energy, directed on a beam path to an object to be imaged; one or more time-of-flight (TOF) detectors arranged on the beam path to detect incidence of beam protons and generate output signals indicative thereof with a time resolution substantially less than a time of flight of the protons; and a data acquisition and analysis subsystem coupled to the TOF detectors to receive the respective output signals and (1) calculate TOF values for respective bunches of one or more protons, (2) convert the TOF values to proton velocity values and proton energy values, and (3) use the proton energy values to calculate a corresponding value for a physical property of the object along the beam path, and incorporate the value into elements of a radiographic image of the object stored or displayed in the system.

    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.
