摘要： An optical system for providing a steerable monochromatized source of x-ray or neutron radiation. The system incorporates a radiation source and a Bragg structure reflective optical element. A stage causes the optical element to move relative to the radiation source. Such movement is coordinated with lateral d-layer grading such that Bragg's law of reflection is satisfied for radiation of a given wavelength bandwidth to be reflected at various instances and departure angles.

摘要： An x-ray imaging apparatus for mammography. The apparatus places the focal spot of the x-ray source as close as possible to a compression paddle or into a desired region of tissue. The apparatus comprises an x-ray source, a collimator with conditioning optics which focus and direct x-ray radiation to a metal pseudo-target in the collimator or a needle placed along the x-ray beam, paddles for breast compression and a detector. The pseudo-target re-emits monochromatic x-ray radiation with an energy, intensity, and space distribution that are adjustable in accordance with a desired imaging procedure.

摘要： The present invention provides a method and apparatus for the continuous manufacturing of optical memory or optical memory substrates, and/or optical disks, which includes supplying a web of material to a substrate forming apparatus, embossing a microform image onto a polymeric film, such as an information track structure for an optical device, onto one or both sides of the web with a flat stamper and punching a hole through the web during the embossing. During the embossing, the polymeric material is heated to above the glass transition temperature (Tg). A flat stamper limits the potential for warp in the web, particularly when the web is stabilized in the stamp zone. The disclosed invention is particularly useful in the production of optical disk substrates, such as polycarbonate, having a thickness of 0.6 mm or less.

摘要： This invention relates to novel methods of producing flat and curved optical elements with laterally and depth graded multilayer thin films, in particular multilayers of extremely high precision, for use with soft and hard x-rays and neutrons and the optical elements achieved by these methods. In order to improve the performance of an optical element, errors in d spacing and curvature are isolated and subsequently compensated.
