A sub-pixel 16 bit charge coupled device camera featuring superresolution for the soft X-ray regime is presented. Superresolution images (SRIs) are reconstructed from a set of 4 × 4 individual low-resolution images that are recorded for different sub-pixel shifts of the detector. SRIs have a 1.3 times higher resolution than individual low-resolution images which is close to the maximum achievable enhancement factor of about 1.5 in the X-ray regime under ideal conditions. To characterize this camera and demonstrate its potential, an X-ray microscope setup is used to image different objects at different photon energies.
本文介绍了一种用于软X射线波段的具有超分辨率功能的亚像素16位电荷耦合器件相机。超分辨率图像（SRIs）由一组4×4的单个低分辨率图像重建而成，这些低分辨率图像是针对探测器的不同亚像素偏移进行记录的。SRIs的分辨率比单个低分辨率图像高1.3倍，这接近在理想条件下X射线波段约1.5的最大可实现增强因子。为了表征该相机并展示其潜力，使用了一种X射线显微镜装置在不同光子能量下对不同物体进行成像。
