SP-436 Project Orion: A Design Study of a System for Detecting Extrasolar Planets

Figure 29. Schematic representation of the output signal from a planet {P) and star (S) as the planet traces a path through the fringe pattern of a rotating interferometer (see text). The planetary signal is flat-topped and rich in harmonics at a frequency four times the interferometer rotation frequency. A star centered precisely on the optical axis of the interferometer produces a small dc signal.
