Abstract
In an embodiment, and by way of example only, a vibration isolator is used for coupling between a payload and a base and includes a rod, a magnetic damper, a first spring, and a second spring. The magnetic damper includes a movable section and stationary section. The movable section comprises a conductive material and has an opening through which the rod extends. The stationary section includes a magnet disposed around and spaced apart from the movable section and is coupled to the base. The first spring couples the movable section to the rod. The second spring is coupled to the rod and stationary section. In another embodiment, the vibration isolator also includes a voice coil actuation system.
