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.

In many computer vision tasks
in order to improve the accuracy and robustness to the noise
wavelet analysis is preferred for the natural multi-resolution property. However
the wavelet representation suffers from the dependency of the starting point of the sampled contour. For overcoming the problem that the wavelet representation depends on the starting point of the sampled contour
the Zernike moments are introduced
and a novel Starting-Point-lndependent wavelet coefficient shape matching algorithm is presented. The proposed matching algorithm firstly gains the object contours
and give the translation and scale invariant object shape representation. The object shape representation is converted to the dyadic wavelet representation by the wavelet transform. And then calculate the Zernike moments of wavelet representation in different scales. With respect to property of rotation invariant of Zernike moments
consider the Zernike moments as the feature vector to calculate the dissimilarity between the object and template image
which overcoming the problem of dependency of starting point. The experimental results have proved the proposed algorithm to be efficient
precise
and robust.
