Image on the detector produced in Zemax OpticStudio in nonsequential regime with two input beams tilted at 0.28° and 0.56°. The white cross denotes the optical axis (center of the FOV), the input beams are marked with thin black arrows, and color arrows show ghost contributors produced by the backreflection from the detector and particular optical surfaces. Annotated color arrows correspond to the ghosts produced by the 0.28° input beam, and the remaining arrows correspond to the ghosts produced by the 0.56° beam.
