Paper Abstract

Actuation system design for adaptive optic devices is based upon the nature of the distortions or aberrations to be controlled, requirinc that the vectors describing these wavefront error sources also aid the designer in selecting the number and locations of actuators. The traditional Zernike polynomials give a good optical description of the aberrations, but tend to obscure actuator requirements. An alternate set of surface vectors, sines and cosines radially and circumferentially, is presented which give the designer a good feel for actuation requirements as well as an accurate description of the wavefront. The constraints on nodal density and arrangement driven by orthogonality and finite element modelling considerations are discussed for both vector sets. In addition, a comparison of wavefront description accuracy is presented.
