Résumé

All macroscopic physical pendula undergo various types of damping processes which make them irreversible devices. Their repeated use for detecting cosmological micro-anomalies requires the determination of certain observables with very high precision despite an increased variance due to the strictly nonperiodical pendulum behaviour. Using genofields from Hadronic Mechanics, data processing algorithms involving backward and forward convolutions have been developed. They greatly improve precision in the determination of swinging azimuth, swinging amplitude, swinging period and precession period. To the author’s knowledge, the very weak anisotropy of a long Foucault pendulum has been characterized for the first time experimentally in terms of zero-amplitude swinging period and conservative (Hamiltonian) amplitude oscillations.
