Corrective force solving is a critical technology of the active optics. A method to solve active optics corrective force is introduced
which is based on Householder transform of Zernike polynomial wave front fitting
this method is different from the traditional least square method and Gram-Schmid orthogonal method
because it does not bring ill-conditioned polynomial without constructing normal equation
so it can avoid calculation error
wave front fitting is precision. Based on the coefficient of the Zernike polynomial and the response function of the each actuator
the stiffness matrix of the primary mirror is built
and then adopting the damp least square method to calculate corrective force. Based on this method
cp400m test mirror is simulated many times
the calculation result approve: if the Householder transform is adopted
wave front fitting is precision
the result is stabilization and corrective effectiveness is better.
