Abstract
a. Perfectionnements aux gyroscopes à laser en anneau. b. Gyroscope à laser en anneau comprenant un bloc cylindrique renfermant une cavité résonnante dans laquelle deux faisceaux de laser sont créés ; des moyens réfléchissants montés sur ledit bloc afin de propager les deux faisceaux de laser le long d'une boucle fermée, l'un dans le sens des aiguilles d'une montre et l'autre dans le sens contraire autour de l'axe d'entrée du gyroscope; des moyens de support pour le bloc placés sur l'axe de symétrie du bloc et ayant un axe s'étendant le long de l'axe d'entrée du gyroscope; des moyens élastiques reliant mécaniquement le bloc aux moyens de supports afin de permettre un mouvement angulaire dudit bloc autour de l'axe d'entrée; et, des moyens de compensation couplés au bloc afin de faire en sorte que les signaux de sortie du gyroscope soient débarrassés de l'influence des vibrations mécaniques imprimées au bloc autour de l'axe d'entrée sur un déplacement angulaire appréciable dudit bloc. c. Concerne notamment les systèmes de guidage par inertie.
