Adaptation problems in the space telescope of the millimetron observatory

Abstract

The Millimetron space observatory with a 10-meter optical telescope is now being created in Russia; it is unparalleled in terms of the scale of scientific and technical problems to be solved in the study of objects in the Universe. The amount of information that can be received with this observatory largely depends on the chosen concept and manufacturability of technology that provide for the high quality of imaging by the telescope. Possible technical solutions and concepts that can form the basis for the creation of systems of adaptive correction of distortions of the incident radiation wavefront are considered based on the analysis of distorting factors. Versions of adaptive optics systems for the space telescope are considered and analyzed. The adaptation at the entrance pupil of the telescope is selected and substantiated, implemented with the circuit of parallel information reading by petals of the telescope integrated primary mirror. The circuit is suggested for real-time dynamic adjustment of the telescope adaptive control system by image analyzer signals. It is shown that visible radiation received from a field region shifted from the telescope optical axis with a random misalignment angle can be used as reference.
