Abstract :
[en] We show that due to analogy of atom and optical interferometry a perturbed phase propagates identically in atom and corner-cube absolute gravimeters. To evaluate associated systematic effects, we consider both gravimeters as a linear system in the time domain. This formalism is based on a weighting function earlier derived for a corner-cube gravimeter. As an example, we demonstrate that the corrections for a linear change of gravity are essentially the same for both gravimeters. Application of a common formalism to analyse various systematic effects could reveal possible source of disagreement in comparisons of atom and corner-cube absolute gravimeters.
