Ghost images produced for an input image with two bright pixels (up-right and up-left from the center) representing two plane-parallel beams tilted at 0.28° and 0.56°. Panels a and b: input image and full ghost image, respectively. Remaining panels: ghost image produced by the front surface of the detector glass (panel c), the rear surface of the detector glass (panel d), the rear filter surface (panel e), the front filter surface (panel f), the rear surface of the O3/L5 lens (panel g), the front surface of the O3/L5 lens (panel h), and the rear surface of the O3/L4 lens (panel i). Logarithmic color scale (shown at the top of the figure) is normalized to the intensities of the input beams.
