Precise acquisition, tracking and pointing (ATP) remain a key issue in the use of free-space optical communication systems for deep space missions. The Optical Communications Group at the Jet Propulsion Laboratory is developing a vibration platform to assist with the development and characterization of an ATP system to be used for deep space optical communications. The vibration platform will provide a means for subjecting ATP systems to the vibration spectrum likely to be experienced while onboard a spacecraft. The platform consists of a 61 cm x 61 cm. optical breadboard mounted on a ball bearing pivot that is driven by a single piezo-electric actuator (PZT). The PZT provides motion in a single axis, giving the platform approximately 200 mu rad of angular motion with a bandwidth in excess of 100 Hz. When placed on the platform, the performance of ATP systems can be tested under several cases of vibration. This paper discusses the physical properties of the vibration platform. A model for the system is discussed and experimental performance data are presented.
