Paper Abstract

Precise optical stability requirements for a military laser required the establishment of detailed error and tolerance budgets of the mechanical system. In order to verify these budgets and also to fully understand the true dynamic stability of the mechanical mounts, extensive thermal testing was performed. This paper present a test technique established to provide a consistent testing process from which results could be used with confidence. Utilizing a readily available optical measurement device and impose test fixtures, this technique provides the designer with a powerful evaluation tool to verify design performance. Various types of result can be obtained using this technique, such as: optical element distortion at temperature, unrecoverable static shifting to the mount, dynamic movement effects and repeatability. These results can be further extrapolated into qualitative assessments of the thermal stability of specific mount design technique. When compiled into a design database, this will provide invaluable information for future design choices.
