Abstract
The necessity and possible ways of monitoring the deformations of the primary mirror directly at the BTA telescope during its operation are discussed. The most acceptable methods and control schemes are analyzed. A scheme is suggested on the basis of the pseudoreversal method, which simply and originally solves the control problem based on the experience of AST-1200 telescope with a composite primary mirror. Possible measurement errors of the system suggested for controlling primary mirror deformations are estimated.
