摘要

Reconfigurations of the original optical mounts are required to facilitate the expanding capabilities and diverse science programs at the Navy Prototype Optical Interferometer. The mounts of current interest are tangent-arm gimbaled mounts located in vacuum chambers, remotely controlled, and precisely aligned through a narrow range of motion. In order to achieve the desired large changes in pathway reflections, the articulated range of the mount was increased from 4 to 45 degrees in elevation and from 4 to 90 degrees in azimuth. This increase was achieved on the elevation axis by fashioning and attaching a worm gear device, and a direct-drive type mechanism was used on the azimuth axis. The original alignment resolution and stability were preserved by retaining the high precision tangent-arm actuators. In this paper, we present the design modifications that achieved the form, fit, and function required for remote-controlled reconfiguration and alignment. The mechanical modifications, modes of operation, test results, and reconfigurations are described in detail.
