摘要： An x-ray computer tomograph, having an x-ray source that generates a fan beam of x radiation and having a two-dimensional energy-resolving detector array, both of which are situated on opposite sides of a gantry so that the x-ray radiation passes completely through a test region. A row of detector elements is situated in the plane of the fan beam and is adjoined in at least one direction perpendicular to the fan beam by several additional rows of detector elements. During the measurement, no secondary collimator is positioned between the test region and the detector array. The following equation applies for the width (B) of the detector elements: B=ZP*arc sin(qmax*λ), where qmax is a pulse transmission, λ is a wavelength of the x radiation, and ZP is the distance of the measurement point from the detector.

摘要： According to one embodiment, a micro-electrical mechanical system apparatus includes first and second mirrors that define a cavity. Moreover, a photonic band-gap structure coats a surface of at least one of the first or second mirrors to improve reflectivity. Another embodiment includes a third mirror, wherein the second and third mirrors form a second cavity. The spaces between the mirrors might comprise, for example, a pair of Fabry-Perot filter cavities for a spectrometer.

摘要： An inspection system positions a balancing shim to asymmetrically balance a magnetic field generated by an inductive sensor, which forms part of the inspection system. Additionally, relays and capacitors used to tune the inductive sensor to a desired resonance frequency are geometrically arranged to minimize electrical interference generated by operation of the relays and capacitors. A shielding device, which may be formed on a printed circuit board, protects a magnetic field generated by the inductive sensor from external electromagnetic interference. A slot positioned in the inductive sensor may be used to tune a resonant mode of the inductive sensor to accurately and particularly detect metallic shanks and/or other metallic objects in shoes, socks, and/or clothing.
