Paper Abstract

This presentation describes fast two-axis beam-steering mechanisms known as TABS built at General Scanning over the years. These TABS approximate a two dimensional fulcrum and can be classified by the number of moving optical elements; one, two, or three. Only large motion devices are addressed here. One-mirror small motion TABS have been hotly pursued for SDI applications, and the SPIE Proceedings, Volume 1543, examines a number of them. Conventional gimbals systems have been generously described elsewhere and also are not treated here. In the common gimbals system, the torque motor for the second axis is transported on the structure mounted on the first axis. There are no universally preferred solutions to two-axis beam steering. Each application has evolved its preferred solution. From the point of view of the optics design, large motion devices such as TABS introduce a number of constrains to speed and excursion.
