OBS

Le gravimètre Hoyt [...] dont la sensibilité est exceptionnelle, a un ressort qui est un ruban plat en hélice [...] Quand le ressort s'allonge sous l'effet d'une petite augmentation de gravité, la partie inférieure à laquelle est fixée une masse, tourne d'un angle proportionnel à l'allongement. Cette rotation peut être mesurée très précisément par le déplacement d'une image fine réfléchie par un miroir fixé à la masse.
