STABILIZING THE SIGHT LINE UNDER CONDITIONS OF STRONG VIBRATION EFFECTS
This article deals with the problems of stabilizing the sight line under conditions of strong vibration effects. We analyzed the problems and revealed the main task to solve: the development of high-frequency interference which causes a significant shaking of the sight line. To improve the quality of stabilization due to expansion of the working band, we decided to develop a fast piezo mirror that will allow us to work out the high-frequency component of the interference. The main stages of the device development are presented in this paper. It is important to note that the synthesis of the automatic control system for the piezo platform, which is based on the principle of the closed-loop control system, is of great interest. This paper also presents the main stages of development of the automatic control system. As a result of the work, a new device was designed that is part of the optical path of an optical system subjected to strong vibration effects. The additional mechanical unit (piezo mirror) allowed us to significantly increase the accuracy characteristics of the system as a whole: it was possible to reduce the residual error of working out more than four-fold.
