Conceptual diagrams of the optical systems for three-dimensional X-ray fluorescence imaging. (a) Scanning microscope CT, (b) confocal scanning microscope, (c) full-field microscope CT, and (d) confocal full-field microscope. The object is located at the origin of the Cartesian coordinate system xyz. Incident X-rays travel along the z-axis. The directions of the x- and y-axes are perpendicular to the z-axis in the horizontal plane and the vertical direction, respectively. The optical axis of theX-ray fluorescence detecting system points to the origin along the x-axis. The scan direction that each method needs for three-dimensional imaging is shown as black characters and black arrows.
