摘要: A interferometric optical gyroscope includes an active resonator comprising a half cavity vertical cavity surface emitting laser (half-VCSEL) operating as one of the mirrors that form the ring resonator. The half-VCSEL includes a bottom mirror stack and active layers formed on the bottom mirror stack and has a surface opposite the bottom mirror stack. Lack of a top mirror stack typically found in a VCSEL prevents the half-VCSEL from lasing, thus the half-VCSEL forms a reflective amplifier for the light circulating in the resonator. A single or multiple external light sources can be used to induce two counterpropagating beams in the resonator. Higher finesse due to the internal gain in the resonator enhances the sensitivity of the gyroscope.

摘要: Détecteur miniature à vitesse angulaire, porteur de liquide, à deux degrés de liberté, utilisé en premier lieu pour des applications tactiques, comprenant un rotor porteur de liquide hydrodynamique sphérique, un moteur-couple magnétique permanent et un capteur optique. Tous ces éléments sont disposés de manière à fournir deux axes d'information sur la vitesse angulaire dans un petit boîtier. Les composants individuels peuvent être préassemblés sous forme de sous-ensembles, et stockés et testés individuellement en vue du montage final.

摘要: Der optoelektrische Meßabgriff ist für einen Meßwertgeber geeignet, der in einer um eine Achse drehbaren Halterung beweglich angeordnet ist, wobei die Auslenkung des Meßwertgebers aus einer Anfangsposition als Meßwertwert erfaßt wird. Der Meßwertgeber weist dazu auf einer der Drehachse der Halterung zugewandten Seite eine mit unterschiedlichen optischen Eigenschaften in Codeform versehene Skala (10) auf. In einer axialen Bohrung (3,1) der Drehachse ist zumindest ein Lichtwellenleiter (9) angeordnet , dessen eines Ende auf die Skala und dessen anderes Ende auf ein optoelektrisches Bauelement (8) gerichtet ist, wobei das optoelektrische Bauelement (8) mit einem die Drehachse der Halterung lagernden Gehäuseteil (1) fest verbunden ist.

摘要: A gymballess, two axis rate gyroscope in which an inertia rotor is keyed on the electric motor shaft. The motor shaft comprises a flexible part (flexure shaft) adapted to flex upon precession of the inertia rotor in consequence of an angular velocity input around either of two axes normal to each other and both normal to the rotor spin axis, and an end portion extending beyond the inertia rotor in a direction away from the electric motor (deflector). The gyroscope further comprises non-contacting measuring means in association with said deflector for detecting any deflection thereof.

摘要: The present invention provides a control moment gyroscope (100) that overcomes many of the limitations of the prior art. The control moment gyroscope (100) provides a radial actuator mechanism (110) to provide rotation to an inner gimbal assembly (102) around a gimbal axis. The radial actuator mechanism comprises a circular ring (111) at the midpoint of the gimbal axis, the circular ring (111) extending around the outer periphery of the inner gimbal assembly housing. The radial actuator mechanism (110) rotates the inner gimbal assembly (102) around the gimbal axis through the use of a non-contact motor that provides rotational force directly to the outer perimeter of the inner gimbal assembly (102). Because the inner gimbal assembly (102) is rotated from the midpoint of the gimbal axis, a torque module assembly at the end of the gimbal axis is not required. Thus, the overall length of the control moment gyroscope (100) can be reduced. Additionally, the cost and life limiting attributes of the torque module assembly can be eliminated, and the operational bandwidth of the gyroscope (100) increased. Finally, because the inner gimbal assembly (102) is rotated from the outer perimeter, the torque provided to the inner gimbal assembly (102) is naturally increased by the leverage arm of the inner gimbal assembly (102).

摘要: A miniature two degree of freedom fluid bearing angular rate sensor used primarily for tactical applications includes a spherical hydrodynamic fluid bearing rotor, a permanent magnet motor/torquer, and an optical pick-off, all of which are arranged to provide two axes of rate information in a small package. The individual components can be pre-assembled as sub-assemblies, and individually stocked and tested for final assembly.
