Abstract

Operating posture of complicated opto-mechanical structures critically matter gravity-induced distortion of the structure, and further affect optical performance. With the aim to solve this problem, determination of operating postures of a supporting system of a KDP crystal is studied. A concept of key stiffness component is firstly proposed in this paper, as far as the authors are concerned, taking advantage of which gravity-induced distortion of the supporting system is analyzed, as well as the rotation of the KDP crystal that is cased by the distortion of the supporting system. Furthermore, effects of operating postures of the supporting system on the distortion of the supporting system and the rotation of the KDP crystal are investigated. It is demonstrated that key stiffness component is of great insignificance to distortion of the supporting system, and it could function as a guidance in determination of operating posture of the supporting system.
