FT-IR Interferogram Sampling Validation and Correction

The velocity profile of the Midac looks like this. The applied 100 Hz disturbance can be clearly seen here. The data range corresponds to 4 cm-1 operation. or 4500 fringes of total retardation. There are two zero crossings per fringe. It is interesting to note the asymmetry in the mirror turnaround.
