We present the optimization of a Fabry–Perot velocimeter designed to measure speed at a few millimeters per second with a relative uncertainty of 10-8. We focus on the accuracy and the optimization of the Fabry–Perot, with a review of the uncertainties related to the geometry, the beam shape, and the Doppler frequency measurement. These errors are quantified to ensure that the required accuracy is reached. We then describe the practical implementation and show the results.
