Uniformity of response. (a) A flat-field image recorded by the lens-coupled detector. The field of view is limited by the size of the phosphor, not by that of the CCD chip. (b) A flat-field image recorded by the fiber-coupled detector. The horizontally elongated area in the center with low intensity was caused by damage resulting from prolonged irradiation, most probably owing to browning of the optical fiber. These images were obtained with an X-ray energy of 23 keV. (c) Horizontal line profiles of the images at the center of images in (a) and (b). (d) Chicken-wire pattern in the fiber-coupled detector.
