This simulator applies to our standing
wave interferometer experiment, interferometer 3. The path C4 is parallel to
the expected aether wind, which in this case is shown on the E-W axis. The
interferometer is rotated 180 degrees in the simulation to anti-parallel to
the wind. A fringe shift is expected through the standing wave sensor (SWD)
due to the path effect since the standing wave moves its position with
respect to the SWD, due to a phase shift between the two
counter-propagating waves. This fringe
shift is canceled by the change in the clock frequency of the laser as it
rotates, which pushes the position of the standing wave back through the SWD
in the opposite direction. The values in green are adjustable. See the
experimental write-up for more details. Note: Clock Effect only applies to
one way paths - all two way paths cancel out. Avg. sin or cos value over 90
deg. = 0.636619783
