Friction Effects on Inertia Compensators used for Heliostat Base Motion Isolation.
Abstract
The base motion isolation of an optical beam deflector with a two-axis gimbal support (heliostat) is discussed. The use of an auxiliary inertia coupled between the elevation gimbal and the heliostat mirror to produce a compensating torque referred to as a gear compensator and a belt compensator are presented. The direction isolation from base motion are determined. The effect of coulomb friction on the compensator action of a gear compensator is evaluated. Such friction-produced pointing error is shown to be reduced by the use of a combined inertia compensator utilizing both the belt and gear compensators simultaneously. (Author)
