Abstract
In this paper the characteristics of a test bed for checking the theoretical behavior of a multi reflection interferometer are described. This optical interferometer has to be coupled to a shaker for the absolute determination of the vibration amplitudes. Its capability of producing four reflections on the measuring beam on the vibrating table, before its recombination with the reference beam, allows to extend the frequency limit at which the optical signal is still satisfactory. The test bed reproduces the working conditions, including the limitations to tilting, optical path length, alignment... and has the objective of experimentally confirm the feasibility study.
