Abstract:
1. An active damping system for damping rotation of a sensor mounted to rotate about two axes of rotation, said active damping system comprising: a first speed measuring device for providing speed measurement data correlated to rotation of said sensor in a first direction about a first axis of rotation; a first torque generating device for generating a first damping torque in opposition to rotation of said sensor in said first direction and having a magnitude dependent upon said speed measurement data provided by said first speed measuring device; a second speed measuring device for providing speed measurement data correlated to rotation of said sensor in a second direction about a second axis of rotation; and a second torque generating device for generating a second damping torque in opposition to rotation of said sensor in said second direction and having a magnitude dependent upon said speed measurement data provided by said second speed measuring device.
