| Popis: | A new wavefront correction algorithm for adaptive optical systems that implements the sequential elimination of aberration components is proposed. The criterion by which correction is guided is the square of the focal spot radius. The operation of the algorithm has been simulated for two fundamentally different mode bases—the generalized Zernike modes and the generalized influence functions of the actuators of the deformable mirror used. The method for obtaining these bases is described. It is shown that, for a wavefront of a complex shape, the correction is more accurate in terms of influence functions, and Zernike modes are better suited for correcting aberrations of lower orders. |
